Political parties are putting together their manifestos for May's general election. Here's a guide to where they currently stand on the issues voters say they care about most (according to pollsters IPSOS Mori).
Conservatives: David Cameron wants to make migrants wait four years before they can claim certain benefits, such as tax credits, Universal Credit, or get access to social housing. He wants to stop migrants from claiming child benefit for dependents living outside the UK, and remove those that have failed to find work after six months. Mr Cameron has promised to put reform of EU free movement rules at the heart of his renegotiation of Britain's relationship with the EU. He has ruled out a temporary cap on migrant numbers or an "emergency brake" on EU freedom of movement rules - ideas both mooted in recent months, saying this would be less "effective" than reducing the incentives for people to come to the UK. The party has a continuing goal to bring net immigration down to below 100,000 people a year (it currently stands at 243,000).
Labour: "Stronger" border controls to tackle illegal immigration with "proper" entry and exit checks. "Smarter" targets to reduce low-skilled migration but ensure university students and high-skilled workers are not deterred. Employment agencies who only recruit abroad will be outlawed while the fines for employing illegal immigrants will be increased.
Lib Dems: Reintroduce exit checks at borders, so the government can identify people who are overstaying their visa. Will require all new claimants for Jobseekers Allowance to have their English language skills assessed, with JSA then being conditional on attending language courses for those whose English is poor. Ensure that EU migrants have to "earn" their entitlement to benefits.
SNP: Allow the devolved government to have control over immigration to Scotland, and introduce a Canadian-style earned citizenship system to attract highly-skilled immigrants.
Plaid Cymru: Oppose a points-based system. Support the right of asylum seekers to work in Wales while they wait for status decisions to be made. Lobby the Westminster government to ensure that they shut "detention" centres.
UKIP: Introduce an Australian-style points policy, used to select migrants with the skills and attributes needed to work in the country - covering people from inside and outside the EU. Bring net immigration down to 50,000 people a year. Priority lanes for UK passport holders. Increase UK border staff by 2,500. Tougher English language tests for migrants seeking permanent residence. Opt out of the Dublin treaty to allow the UK to return asylum seekers to other EU countries without considering their claim. Anyone who currently has the legal right to live, work, or study in the UK would not face deportation in the event of the country's withdrawal from the EU.
Greens: Progressively reduce UK immigration controls. Migrants illegally in the UK for over five years will be allowed to remain unless they pose a serious danger to public safety. More legal rights for asylum seekers.
Taxes and the economy
Conservatives: Eradicate the deficit by 2018 and secure an overall budget surplus by 2019-20. Achieve this by spending cuts, not tax rises, while raising NHS spending. An income tax cut for 30 million people by 2020. Tax would start to kick in at £12,500 a year, instead of £10,500. This will cost £5.6bn. The higher tax rate, 40%, would start at £50,000 instead of £41,900, again by 2020, at a cost of £1.6bn. This will be paid for through £25bn in additional spending cuts and economic growth. No increases in VAT.
Labour: Get the current budget into surplus and the national debt falling "as soon as possible in the next parliament". No additional borrowing for new spending. Reintroduce the 50p top rate of income tax for earnings over £150,000. Cut income tax for 24 million people by bringing back the 10p rate, paid for by scrapping the Married Couples' Tax Allowance. Bring in a "mansion tax" on properties worth over £2m, to raise £1.2bn. A tax on bankers' bonuses. A 5% pay cut for every government minister. Push for UK overseas territories to be put on an international blacklist if they refuse to co-operate with a drive against tax avoidance. No increases in VAT or National Insurance contributions.
Lib Dems: Raise the personal allowance - the point at which you start paying income tax - to £11,000 in April 2016 and then to £12,500 by 2020. "Strict new fiscal rules" to ensure the deficit has gone by April 2018, with the wealthy contributing the most. The Lib Dems invented the "mansion tax" but in contrast to Labour have set out how it would operate - along similar lines to council tax bands. There are also Lib Dem plans to increase capital gains tax - paid on profits from second homes or shares - from 28% to 35%. Impose an additional 8% rate of corporation tax on UK banks to raise an extra £1bn a year to help pay off the deficit.
SNP: Oppose UK plans in the Infrastructure Bill which will allow oil and gas drilling and hydraulic fracturing beneath people's homes without consent. Invest in offshore wind farming. Support an international bank tax and limits to industry bonuses.
Plaid Cymru: Build a Green Skills Construction College, specialising in green energy. Establish a publicly-owned energy company. Establish a publicly-owned Bank of Wales business investment bank. Enforce a living wage. Give devolved nations an equal say in institutions that affect everyone's lives, such as the Bank of England.
UKIP: Increase the personal allowance to the level of full-time minimum wage earnings, about £13,500, by 2020. Abolish inheritance tax. Introduce a 35% income tax rate between £42,285 and £55,000, at which point the 40% rate becomes payable. Set up a Treasury Commission to design a turnover tax on large businesses. Cut foreign aid budget by £9bn a year. Scrap HS2. Save £8bn a year in membership fees by leaving the EU. Lower the VAT rate charged on restorations to listed buildings.
Greens: People earning more than £100,000 a year would pay 50% income tax. Wealth tax of 1% to 2% on people worth £3m or more. Renationalise the railways and energy companies. Scrap HS2. Allow councils to impose extra business rates on out-of-town supermarkets to fund small local businesses. Crackdown on tax avoidance by multinationals. Allow "the current dependence on economic growth to cease, and allow zero or negative growth to be feasible without individual hardship". Commit Britain to a "zero carbon" future. Cut rail and bus fares by an average of 10%. Enforce a cap on bankers' bonuses.
Conservatives: Chancellor George Osborne says he will put an extra £2bn into frontline health services across the UK, which he described as a "down payment" on a plan drawn up by NHS bosses calling for an extra £8bn a year above inflation by 2020. In England, everyone would be able to see a GP seven days a week by 2020. Recruit 5,000 more doctors.
Labour: Shadow chancellor Ed Balls said Labour would commit an extra £2.5bn a year above Mr Osborne's plan. The money will come from three sources - a new "mansion" tax, clamping down on tax avoidance by big corporations and a new tax on tobacco companies. Patients in England would get a GP appointment within 48 hours and would not have to wait longer than a week for cancer tests and results. Scrap the Health and Social Care Act and end "creeping privatisation" of the NHS. Integrate health and social care services into a system of "whole-person care". Give greater priority to mental health services. Replace the Cancer Drugs Fund in England when it runs out in 2016 with a £330m fund to improve access to innovative cancer drugs, surgery and radiotherapy. Recruit 5,000 more healthcare workers to help patients stay in their homes and introduce new safety checks to identify people at risk of hospitalisation. Prioritise child mental health by increasing the proportion of the mental health budget spent on children.
Lib Dems: An extra £1bn for the NHS every year, to be funded by - amongst other things - making higher earners pay more tax on their shares. Half of this will go towards mental health. Ensure that spending on the NHS rises in line with growth in the economy. People who need therapy for conditions such as depression will be guaranteed treatment within 18 weeks. For young patients experiencing psychosis for the first time treatment will be provided within two weeks of being referred by a GP. This is all going to happen from April, with more mental health targets to follow if the Lib Dems return to government. Wants a cross-party review of the future of NHS funding.
SNP: Reduce the number of senior managers in the NHS by 25% over the next parliament. Streamline the work of health boards. Real terms increases in year-on-year NHS spending.
Plaid Cymru: Recruit 1,000 extra doctors to the Welsh NHS over two terms of a Plaid government. Offer financial incentives for recruiting doctors to areas and specialisms where there are, or are predicted to be, shortages. Encourage innovation and attract more research funding, in part by increasing research and development funding as government finance allows. Improve training for postgraduate doctors and stop them being used to "plug gaps" in staff rotas. More recruitment from within the EU to fill vacancies and using international doctors to staff the NHS while a new generation of Welsh doctors are trained.
UKIP: An extra £3bn per year in NHS funding paid for by quitting the EU and through "middle management" cuts. Keep NHS free at the point of delivery. Stop any further use of PFI, and encourage local authorities to buy out their PFI contracts early where it is affordable to do so. Ensure all visitors and migrants who have been here for fewer than five years have NHS-approved medical insurance as a condition of entry to UK, with £200m of the £2bn saved to be spent on ending hospital parking charges in England. Bring back state-enrolled nurses and return powers to matrons. Monitor and Care Quality Commission to be replaced with elected county health boards. Stop spending £90m a year on gastric band and breast enhancement operations.
Greens: Funding to be diverted away from centralised facilities towards community healthcare, illness prevention and health promotion. Stop privatisation. Abolish prescription charges.

A complete ban on the promotion of tobacco and alcohol products, including sponsorship.

Conservatives: Protect England's schools budget - from reception entry at age four or five to the end of GCSEs at 16 - in cash terms although funding per pupil will not keep pace with inflation. Pre-school and post 16 education not ring fenced. Convert up to 3,500 more schools judged by Ofsted to "require improvement" into academies. "War on illiteracy and innumeracy". State primary schools in England that repeatedly failed to have a proportion of year-six pupil pass times tables and writing tests be forced to become academies, or have sponsorship replaced if already an academy. Opposed to giving votes to 16 and 17-year-olds for UK-wide general elections and local elections in England.
Labour: Increase the overall education budget in England, including schools, nurseries, Sure Start and provision for 16-to 18-year-olds, by at least the rate of inflation, although per-pupil funding is not specifically protected, meaning some of the increase will be eaten up by rising pupil numbers. Parents of primary school children would be guaranteed childcare from 8am to 6pm. The amount of free childcare for three and four year olds would be increased from 15 to 25 hours a week. Compulsory sex and relationship education in all schools.

Plaid Cymru: Introduce a compulsory modern foreign language GCSE in secondary schools and the teaching of modern foreign languages in primary schools. Look at ways to strengthen the teaching of Welsh history and culture. Oppose foundation schools, academies and free schools. Look at moving from a per-pupil funding mechanism to a funding model based on the catchment area.

Greens: Abolish right to buy. Give councils the power to borrow money to build houses or buy them on the open market. Introduce a rent cap to prevent exploitation by private landlords. Set up a living rent commission, to work out how to bring rents back in line with incomes. Home owners unable to meet mortgage payments or under threat of repossession would get right to transfer ownership to the council, at less than market value, and pay rent as council tenants.

Stop paying child benefit for children who don't live in Britain. Scrap what UKIP calls the "detested bedroom tax". Boost "credit unions".
Greens: The party backs a Citizen's Income, a fixed amount of £72 income a week to be paid to every individual, whether they are in work or not, to be funded by higher taxes on the better off and green levies. But in the short-term it would increase the minimum wage to £10 by 2020. Ban zero hours contracts. Axe the "bedroom tax". Abolish the work capability assessment and restore the level of the former disability living allowance. Scrap the government's welfare cap, which limits the maximum amount a household can claim annually to £26,000 a year.
