Children in care 'let down for too long', says David Cameron
The government is to pass new laws to encourage adoption in a bid to improve the chances of children in social care in England, David Cameron has said.
Writing in the Sunday Times, the PM promised "zero tolerance" of state failure around social care and a new covenant for those leaving care.
New laws will encourage the permanent adoption of children, even when it overrides family ties, he added.
Labour said government cuts had already harmed students and working families.
The government will outline the plans in the Queen's Speech on Wednesday.
The speech - which will mark the official state opening of Parliament - will reveal the laws the government hopes to get approved over the coming year.
It is expected to include measures aimed at encouraging top UK universities to do more to improve social mobility and more help with energy costs for poorer households.
BBC political correspondent Iain Watson said Mr Cameron was "keen to demonstrate that his current focus on the EU referendum was not at the expense of the domestic political agenda".
In January, Mr Cameron promised an "all-out assault on poverty" with a series of social reforms to include better mental health services and mentoring schemes.
Mr Cameron wrote that the government would legislate to encourage permanent adoption - even if it meant children were not placed with relatives.
He said he was "unashamedly pro-adoption" and criticised courts and social workers for favouring "less stable placements" with distant relatives, rather than with adoption families.
"We will legislate to tip the balance in favour of permanent adoption where that is the right thing for the child - even when that means overriding family ties", he wrote.
"For too long, whether through misguided notions of what is right or sensitivities about not wanting to cause offence, we have let the most vulnerable in our country down. That needs to change."
Reforms will also set "new, demanding standards" for all child and family social workers to meet by 2020, he added.
A new regulator will be introduced to oversee the system, he said.
Instead of "rigid rules and processes", social workers will be allowed to use their "experience and common sense to make good judgements".
'More personalised help'
Mr Cameron pledged people leaving care would be given "far more effective support", with the introduction of the UK's first care leavers' covenant.
"This will be a promise, set out in law, to everyone who has been through the care system, making sure that local authorities set out clearly what they are entitled to locally - including housing, jobs and healthcare."
Care leavers will be given "more personalised help", with every person under the age of 25 given a mentor.
The prime minister wrote: "Our priorities are clear: with our economy now fundamentally stronger, I want the next four years to be a period of great social transformation in Britain."
The plans also include changes to the prisons system, new powers to tackle extremism and measures to extend educational opportunity, he added.
