Steve Baker, who leads Conservatives for Britain, says he's "proud" that the Leave side have set out details of their plans for what would happen after Brexit - to cut VAT on domestic fuel, get immigration under control and start doing our own trade deals.

"This is a positive vision to take back control, spend our money on our priorities," he goes on.

He says it's "quite absurd" to suggest the UK wouldn't be able to trade with the rest of the EU once on the outside.

"This will be absolutely fine."

Steve Baker says he is "absolutely confident" the chancellor "would not bring forward this Budget after the vote", stressing again that he believes it is only "a campaign tactic". 

He says all of the big players in government "would change their tune very quickly" and the chancellor, prime minister and governor of the Bank of England "would all be united very quickly in creating stability and calm, promoting prosperity, whatever the outcome of the vote".

"They will stabilise the markets and we will go on as before," he adds.

Steve Baker, one of the MPs to sign that letter to George Osborne, denies there is "open warfare" at his "level" of the party.

He accuses Mr Osborne of "whipping up fear to secure a political objective".

He says it is "just a scary story, a campaign tactic", and is viewed by many in the party as "derisory".

This just in to us from a senior Labour source.

They say: "This may be a natural Tory approach, but no Labour chancellor would respond to an economic shock in this manner. And neither did Alistair Darling in 2008. 

"Any credible economist would tell you that raising taxes or cutting spending or both in response to an economic shock is the wrong thing to do. It's deeply worryingly that this suggests the current Tory chancellor thinks this is a sensible response."

George Osborne says the alternative to that "chaos in the public finances" is a vote to remain in the UK next Thursday.

"We're going to be stronger safer, better... that's what we want to see, that's on offer. 

"Let's vote for the positive upside, not all the negative consequences of quitting."

Fifty seven of your own MPs are saying they'd block the emergency Budget you say you'd write post-Brexit, Mr Osborne is told.

He deflects first, stressing again how unusual it is to have a Tory and Labour chancellor agreeing.

He then answers by saying that "Conservative MPs don't like raising taxes, least of all me.

"But equally, Conservatives understand and some Labour MPs understand that you cannot have chaos in your public finances and you have to take the necessary financial measures.

"The Conservative government would do what's needed," he says, adding that Conservative MPs had reluctantly had to vote to back a rise in VAT after 2010 to fix the then public finances.

Is there any more that can be done on freedom of movement within the EU to address voter concerns about immigration, Mr Osborne is asked.

He puts off replying to that question by stressing again how bad Brexit would be for Britain, especially for the less well-off. 

"There's no coming back, it would be a one-way exit."

Mr Osborne then comes back to freedom of movement and says "the short answer is no", there's nothing more that will be done, and that's because there's a plan in place already, he says, to restrict access to benefits for migrants and tackle what he calls "the abuse of free movement".

Mr Osborne says raising taxes or cutting spending for key public services like the NHS would be unavoidable if the UK left the EU.

But that would mean breaking your manifesto promises, it's put to him.

The chancellor says "the country would not be able to afford the size of the public services we have at the moment".

"You have to cut your cloth accordingly."

How can you possibly predict austerity for years to come, the chancellor is asked. He replies by quoting economic experts and big businesses who are worried about Brexit, and says we should "look at the markets", which some say are already showing jitters about the possibility.

George Osborne doesn't accept that there were already signs of slowing growth in the UK, although he accepts there are "challenges".

"Cutting off your links with your closest trading allies... is not the answer to any of those problems."

George Osborne is now on the Today programme. He says this is the first time a Conservative and Labour chancellor have agreed on the impact Brexit would have on the public finances.

"It would be self imposed austerity for many years to come," he says.

Downing Street have sought to play down a threat by 57 Conservative MPs to block a planned emergency Budget by the chancellor if the UK votes for Brexit.

Number 10 say an "economic reality" would "kick in" if the UK voted to leave.

They have also suggested there would be a majority of MPs  - including Labour MPs - prepared to support measures to shore up the public finances.

In other words, they believe such a Budget could pass with the support of Oppositon MPs.

Far from containing any political fallout, today's Daily Express is predicting it, claiming to have heard whispers that David Cameron is reportedly "considering , externalsacking his home secretary for refusing to campaign to stay in the European Union".

The paper says the PM "is allegedly seething at Mrs May’s relative absence from the debate".

It claims her "leadership ambitions are likely to have contributed to her decision not to campaign", but it quotes one "stringent ally" of Mrs May as insisting “she has been campaigning for Remain, but it has been drawing less attention".

The Daily Telegraph

Several papers discuss the so-called road map being set out by the Leave side, among them the Daily Telegraph. 

Its editorial says that by laying out a plan like this, Messrs Johnson and Gove are attempting "to contain the political fallout that would merely fuel market uncertainty". 

The paper thinks it would be "wise", as they suggest, not to rush to serve notice of Britain's intention to leave the EU by triggering Article 50 of the Lisbon Treaty - and instead to begin with informal talks in Brussels before any such triggering.

Backing that strategy, it adds: "While losing would be a calamity for Mr Cameron, we would hope he will resist doing anything precipitate likely to damage the country and his party." 

The most drastic warning yet in a campaign laced with fear, has met its most drastic response... Whatever you decide a week tomorrow, the governing party may be changed for good.

Fifty-seven Tory MPs have issued a joint statement warning the chancellor that his position would be "untenable" if he attempts to cut the budgets of the NHS, police and schools if Britain votes to leave the EU.

George Osborne and Alistair Darling have laid out £30 billion worth of tax rises and spending cuts they say would be necessary if Leave win the referendum on 23 June.

The MPs, including Iain Duncan Smith, Liam Fox and Owen Paterson, warn they "cannot possibly allow" cuts to services the Conservatives promised to protect in their 2015 manifesto.

'We find it incredible that the chancellor could seriously be threatening to renege on so many manifesto pledges," the statement said.

"It is absurd to say that if people vote to take back control from the EU that he would want to punish them in this way.

"We do not believe that he would find it possible to get support in Parliament for these proposals to cut the NHS, our police forces and our schools.

"If the chancellor is serious then we cannot possibly allow this to go ahead. It would be unnecessary, wrong and a rejection of the platform on which we all stood.

"If he were to proceed with these proposals, the chancellor's position would become untenable.

"This is a blatant attempt to talk down the market and the country. The chancellor risks doing damage to the British economy in his bid to win this political campaign."

Financial Times

Warnings about the impact of Brexit lead today's Financial Times, which says there was "global market upheaval" on Tuesday, prompted by fears of a Leave vote. It saw "investors rushing for safety and sending the UK's currency and stocks to their lowest levels in months".

In its editorial, the paper criticises those who say the EU is a drag on UK growth. It says there is "mounting evidence the eurozone may have turned the corner", and even if it hasn't, "the Brexit camp is wrong to suggest a deepening crisis will inevitably require further bailouts".

Even if it did, the leader adds, the impact of leaving the EU "would be more costly, in terms of UK exports and jobs, than any hypothetical future bailout".
