Newspaper headlines: 'New nuclear age' and 'raid' for UK tech firm
The birth of what the i calls Britain's "new nuclear age" makes headlines in several of Tuesday's papers.
MPs voted by 472 to 117 in favour of renewing the Trident nuclear weapons system, and the i highlights PM Theresa May's claim that she would be prepared to authorise a strike.
Under the headline "nuke kid on the block", the Sun says Mrs May used her first House of Commons appearance as prime minister to say abandoning the nuclear arsenal would be a "reckless gamble".
The Daily Mail says successive governments have done "nothing but procrastinate" over the issue, and the paper gives Mrs May "full marks... for finally getting something done".
But it says there is "more to the defence of the realm than renewing Trident", and there must be no repeat of past underfunding of UK armed forces.
The Mirror says building four new nuclear submarines would cost £31bn, with a total cost of £179bn over their lifetime.
"Trident is the extortionate insurance policy Britain doesn't especially want and will probably never need, but can't quite face the future without," the i's Oliver Duff writes.
The Telegraph says Labour leader Jeremy Corbyn was heckled and accused of lying by his own MPs as he opposed the renewal of Trident.
Several papers criticise Mr Corbyn's stance - with the Sun calling him a "hard-left terror sympathiser who wouldn't fight back in a nuclear assault".
Mr Corbyn is facing a leadership challenge amid a "barrage of criticism" from MPs, but the Times says his popularity among grassroots Labour members has grown.
In the Guardian, Polly Toynbee suggests there could be an "epic rightward shift" in the next Parliament and says a "serious" Labour leadership would be working hard to win over voters in areas which backed Brexit in the EU referendum.
While Labour's contest continues, commentators pick out a new "bright-eyed" and "fresh-faced" Conservative backbencher - David Cameron.
In the Telegraph, Michael Deacon says Mr Cameron got a "little cheer of encouragement" from some fellow MPs as he appeared in the Commons for the first time since standing down as PM.
There are opposing views over the agreed purchase of UK smartphone microchip designer ARM Holdings by Japanese technology giant SoftBank.
In the Financial Times, Softbank's chief executive says the deal highlights his confidence in the post-Brexit UK economy - a view echoed by a spokesman for Mrs May.
In an editorial, the paper says the move is a "welcome shot in the arm at a time of uncertainty".
But it warns that Britain cannot "sell its way to glory", and says the country must get better at "nurturing the strategic businesses it creates".
The Telegraph says the deal is a "useful corrective" to the "misplaced gloom that some disappointed politicians sought to promote after the EU referendum".
It says Britain's openness to foreign ownership of big companies has been a "source of great strength", and Mrs May should resist the "mood of closed-door protectionism sweeping so many other countries".
"With the pound having fallen sharply, there will soon be more raids on British firms. We need a strategy to ensure they don't harm the economy and cost jobs," the Mail comments.
The Times says the deal "points to weaknesses of the British economy that are in danger of being intensified outside the EU".
What the commentators say
'Instant air con'
Parts of the Midlands and southern England will be hotter than Hawaii today as temperatures reach 95F (35C), the Express reports.
It says health and weather experts have issued warnings due to the heat, with the elderly and anyone with medical problems advised to take extra care.
The Times publishes a guide on how to keep cool in the heatwave.
Its tips include a cold compress made by putting a sock full of rice in the freezer, and "instant air con" made by hanging a damp sheet in front of an open window.
Sleep expert Sammy Margo suggests having a warm shower before bed then cooling while drying, and lying "spreadeagled" while asleep because it's "cooler than curling up in the foetal position".
Even more chilling, however, is the Daily Star's warning that "monster killer jellyfish" are heading for Britain.
The high temperatures will make UK beaches a magnet for Portuguese man-of-war jellyfish, which have "knife-like poisonous stings", the paper explains.
- Hospital warning: If you are looking for Pokemon please don't come to A&E: A hospital has said people may not visit simply to play Pokemon Go, after it became a focal point for players of the popular game, the Telegraph reports.
- I want to be God: The Mirror says Zlatan Ibrahimovic has vowed to top Eric Cantona's legendary status and become "the God of Manchester United".
- Liverpool shows red card to "aggressive homeless": A system of football-style yellow and red cards has been introduced to tackle "intimidating" behaviour by some rough sleepers, the i says.
- Hunters out to kill lynx: Professional trackers are hunting a lynx which escaped from Dartmoor Zoo, the Sun reports. It says the hunters want to "bag selfies with his body".
Several papers report on the situation in Turkey following the failed coup in the country on Friday.
The Financial Times says US and European leaders have warned President Recep Tayyip Erdogan to use restraint in his "increasingly wide-ranging crackdown against plotters".
Writing in the paper, Peter Westmacott says President Erdogan's response so far suggests he is "keener to crack down than lighten up" on issues like inclusivity, freedom of the press, rule of law and tackling corruption.
If the "purge" is extended to include opposition voices, the president's attempt to solidify power will "backfire", according to Lina Khatib, of the Chatham House think tank.
In the Mirror, she says such action would also "strain relations" with European countries.
Germany has said any attempt by Turkey to reinstate the death penalty for the plotters would derail the country's bid to join the EU, the Guardian reports.
