The Vote Leave battle bus is at a sunny Carmel racecourse in Cumbria. On board is Northern Ireland Secretary Theresa Villiers, setting out a very different vision to PM David Cameron earlier.

"I believe we're going to be hugely successful as an economy outside the EU," she says. "If the EU is so great for jobs, why do they have terrible levels of youth unemployment in so many places in the eurozone in particular?"

She adds:

London Mayor Sadiq Khan is asked why Labour leader Jeremy Corbyn won't agree to campaign with David Cameron, as he has done.

"I'm here speaking at the mayor of London, campaigning with the prime minister to persuade as many Londoners as I can, and those around the country, why a vote to Remain is so important," Mr Khan said.

"Jeremy Corbyn is doing a huge amount of campaigning to persuade people around the country why it's in our interests to remain in the European Union - and I'm sure he'll carry on doing that until 10pm on June 23."

Ken Clarke says it is "quite absurd" that there are still people serving indeterminate sentences in prison after Parliament abolished them during his time as Justice Secretary.

Current Justice Secretary Michael Gove has ordered a review of the position of thousands of prisoners serving a sentence known as an IPP or Imprisonment for Public Protection.

"I would have let them out when they finished their sentences," Mr Clarke told Today presenter John Humphrys.

BBC political correspondent Ben Wright says Sadiq Khan sharing a platform with David Cameron "shows how much this referendum is reshaping politics, at least temporarily".

"Just a month ago David Cameron was being very, very strong in his attacks on Sadiq Khan," Ben tells the BBC News channel, but is now "lavishing praise on him".

He adds: "In return, Mr Khan was fairly warm towards the prime minister."

The five pledges they set out are an attempt to "nail down the core Remain message" and contain "something for Tories, something for Labour voters", Ben says.

David Cameron and Sadiq Khan unveiled a "five point guarantee card" of pledges of what voters will get if they vote to Remain. According to the prime minister, they are:

1. Full access to the EU single market

2. Protection of workers' rights

3. "A safer Britain" with co-operation with other EU states

4. The UK will keep its "special status" within the EU, outside the euro, the Schengen passport-free area and with an opt-out from the EU's aim of "ever-closer union"

5. Stability

"I myself am a Eurosceptic," David Cameron tells Remain supporters in London. "I'm sceptical about some of the things Europe has done."

He argues that the ability to criticise the EU is "a cause of strength in our campaign... we're levelling with people, something the other side refuses to do".

"I'm proud to be here with the mayor of London - with the Labour mayor of London - on this vital, vital issue," David Cameron says.

He congratulates Sadiq Khan on becoming mayor, adding: "Someone who is a proud Muslim, a proud Brit and a proud Londoner can become mayor of the greatest city on Earth. That says something about our country."

Like Mr Khan said of him, the prime minister says he expects many disagreements with the London mayor but they are part of "an incredibly broad campaign" in favour of EU membership.

London Mayor Sadiq Khan tells Remain supporters that "more than half a million jobs" in London depend on the UK's membership of the EU.

"A vote for Remain means jobs and opportunities," he argues. He also claims it means measures to fight climate change, "workers' rights protected and more rights for women".

Mr Khan says London has "never taken an isolationist approach", describing the capital - and the UK - as "outward-looking".

And he urges young people to "get involved" and register to vote.

Labour Mayor Sadiq Khan and Prime Minister David Cameron greet Remain supporters in London.

"Let me be quite clear from the beginning," Mr Khan says.

"There are many things on which the prime minister and I will disagree. But what's really important is when it's in Londoners' interests for the mayor and the government to work closely together, we will work closely together."

The UK Foreign Office has been spending over £1m a year on an international security alliance that was abolished in 2011, the BBC has discovered.

In the past five years the department has paid around £5.5m to the Western European Union, which is now defunct.

Critics said it was a waste of taxpayers' money but the Foreign Office says the UK has been pushing to get the WEU fully closed as soon as possible.

The payments were revealed by a Freedom of Information request.

"David Cameron is to reject demands from Tory rebels that he should set a date for his departure from No 10," says the Times., external

"The prime minister will dare backbenchers to carry out a threat to depose him in the wake of the European Union referendum that has split his party.

"Conservative MPs backing the Leave campaign broke cover yesterday to call for a vote of no confidence regardless of the result. They accused Mr Cameron of telling 'outright lies' and said that his future in office was untenable.

"The party’s civil war threatens to effectively put his leadership on the ballot paper."

The government has responded to Eton College head Lord Waldegrave's claim that it's "social mobility agenda" would discriminate against children at fee-paying schools.

A cabinet office spokesperson said: "We are fully committed to increasing social mobility, and building a civil service that represents the country that it serves.

"The proposals we have outlined to measure social background are part of a broad consultation and no legislation is being put forward. While voluntary, we are already hugely encouraged by the number of businesses that are grasping this and helping us to shape these measures and therefore enhance social mobility."

A very different kind of Conservative split is also on the cards, according to the Telegraph., external

"The Provost of Eton College has threatened to resign from the Conservative Party over government plans to make employers ask candidates whether they attended an independent school," the paper reports.

"Lord Waldegrave of North Hill, a former Tory cabinet minister, has told Conservative officials he cannot accept proposals published last week. 

"He issued the warning after Matt Hancock, the Cabinet Office minister, said companies should ask job applicants whether they went to private school, external in an attempt to stop discrimination against the poor.

"His comments puts David Cameron at odds with the most senior individual at the school he used to attend. Lord Waldegrave, who served in the governments of both Margaret Thatcher and John Major, said he believes the prime minister's policy would discriminate against children at fee-paying schools."

Conservative MP Ken Clarke tells Today that David Cameron's "authority will be destroyed" if there is a Leave vote in the EU referendum.

"As we can see, half the campaigners [for Leave] are campaigning because that is their principal hope," he adds. "Who on earth will succeed him, I haven't the foggiest notion."

The pro-Remain former minister calls Conservative Party infighting "damaging to the referendum", adding:

Pro-EU former cabinet minister Ken Clarke has compared Leave campaigner Boris Johnson to US presidential contender Donald Trump.

"He's a much nicer version of Donald Trump but the campaign is remarkably similar in my opinion and about as relevant to the real problems the public face," Mr Clarke told the Today programme.

He also called attacks on David Cameron by pro-Leave Conservative MPs "completely unhelpful", adding: "The personalities get in the way and it's no good turning the Leave campaign into a kind of leadership bid for Boris Johnson."

The Daily Telegraph

The Telegraph, external reports that Eurosceptic Conservative MP Sir Bill Cash "is ready to demand David Cameron goes unless he tones down attacks in the EU referendum".

The Conservative MP, who chairs the Commons Conservative European Scrutiny Committee, told the paper "he has grown infuriated by the Prime Minister’s 'monumentally misleading propaganda' and demanded a more conciliatory tone."

The article continues: "The veteran Eurosceptic said he was 'certainly considering' submitting a letter calling for a no confidence vote and gave the leadership 10 days to drop “inaccurate” warnings over leaving the EU."

Fellow Conservative MP Nadine Dorries suggested the PM would be "toast" after the referendum and another Leave supporter, Andrew Bridgen, external, said Mr Cameron's position would be "untenable".

The World Trade Organisation's former director-general has warned that the UK economy risks a "huge blow" if it relies on the agency's global trading rules in the case of an EU leave vote.

The UK's services would be particularly vulnerable, while manufacturers would face "appalling complexity", Peter Sutherland told BBC Radio 5 Live.

Vote Leave campaigners argue the UK can rely on WTO rules in a Brexit vote.

A high-profile campaigner said Mr Sutherland's fears were misplaced.
