Jeremy Corbyn today said that backing a second Brexit referendum 'is an option' as he called for Britain to stay locked into an EU customs union permanently.

The Labour leader insisted he could do a better job of the Brexit talks than Theresa May, whose deal has taken a hammering from all sides.

And he blasted the PM's divorce package - saying it will make Britain poorer and not guarantee workers rights.

But he admitted that he has not read all of the Brexit divorce bill - which runs to over 500 pages.

And he also said Labour could back another referendum - dubbed a People's Vote - despite last w eek saying Brexit cannot be stopped.

It comes just a day after his trusted lieutenant John McDonnell admitted another referendum is now more likely than a General Election.

Jeremy Corbyn today said that backing a second Brexit referendum 'is an option' as he called for Britain to stay locked into an EU customs union permanently.

Jeremy Corbyn (pictured leaving his Islington home this morning wearing the Marks and Spencer anorak he controversially wore to the Remembrance Day services in London a week ago) is hoping to swoop on the civil war engulfing the Tories to boost Labour's poll ratings

Mr Corbyn tried to swoop on the chaos rocking Mrs May's government to say Laboour could do a better job at the crunch talks with Brussels.

Appearing on Sky News' Sophy Ridge on Sunday, he said: 'We are saying to the Government, you do not have a majority in Parliament for this.

'You don't have a majority of support in the country. You have to go back and do something better.

'We have got to get in place a permanent customs arrangement with the EU.'

He trashed her Brexit deal, telling Sky News that it was a 'one-way agreement' in which the EU 'calls all the shots'.

He said: 'We'll vote against this deal because it doesn't meet our tests. We don't believe it serves the interest of this country, therefore the Government have to go back to the EU and renegotiate rapidly.

'There's 500 pages in this document much of which is quite vague, where's the guarantee on environmental protections, where's the guarantee on consumer protections, where's the guarantee on workers' rights?'

Theresa May received a much-needed boost today as a poll finds that more voters want her to stay on as PM than those who want her ousted

The Labour leader said that if Britain does not do this then the country will lose out on 'investment and development'.

But his comments will infuriate Labour Leave voters who backed Brexit in part because they wanted the UK to break free of the EU ad strike its own trade deals globally.

On a second referendum, he said: 'I think it is an option for the future, but it is not an option for today, because if we have a referendum tomorrow what is going to be on it?'

Theresa May warns that Brexit could be stopped if rebellious Tory MPs force leadership bid Theresa May today warned her rebellious Tory MPs against trying to oust her as PM -saying it will only breed uncertainty and could stop Brexit. The PM confirmed she is set to fly back for more negotiations with the EU this week as she stressed her under-fire Brexit plan is not fully finished. She said the next seven days will be 'critical' for the plan - but her negotiations with Jean-Claude Juncker will focus on the future trade deal. Mrs May is in the political battle of her life to get her divorce package backed and stay on as PM amid a bitter Tory plot to oust her. And stepping up her fightback, she warned the Eurosceptcs trying to oust her their bid risks backfiring and allowing Remainers to thwart Brexit altogether. She told Sky News' Sophy Ridge on Sunday: ‘A change of leadership at this time is not going to make the negotiations any easier and it is not going to change the parliamentary arithmetic. 'It will bring uncertainty and increase the risk that we delay the negotiations, and that is a risk that Brexit gets delayed or frustrated.' Stepping up her fightback against her critics, the PM insisted her deal delivers on Brexit and is in the national interest. In a rare, live interview, Mrs May said: 'This is not about me it is about what is right for the people of this country. It is about what is in the national interest. That is what motivates me.'

And asked if he would support Remain in a second referendum, he said: 'I don't know how I am going to vote, what the options would be at that time.'

Mr Corbyn also squirmed in his seat as he was challenged by presenter Sophy Ridge about his past history as a Eurosecptic.

He also refused to say how he would vote in another referendum - saying he would have to see what options were on the ballot paper.

The Labour leader also denied that by opposing Mrs May's Brexit he is helping to send Britain hurtling towards a no deal Brexit.

But while Mr Corbyn was trying to swoop in the bitter civil war in the Tory Party to boost Labour, Mrs May stepped up her fightback to insist her deal is in the national interest.

She warned her rebellious Tory MPs against trying to oust her as PM -saying it will only breed uncertainty and could stop Brexit.

She told Sky News' Sophy Ridge on Sunday: ‘A change of leadership at this time is not going to make the negotiations any easier and it is not going to change the parliamentary arithmetic.

'It will bring uncertainty and increase the risk that we delay the negotiations, and that is a risk that Brexit gets delayed or frustrated.'

In a much-needed boost for Mrs May, a new poll found that nearly half of Britain's voters want her to stay on as Prime Minister and see through Brexit.

But the Conservatives have lost ground to Labour in the polls after a chaotic week of politics saw Theresa May's party turn on itself over Brexit.

A ComRes poll for the Sunday Mirror and Sunday Express saw the Tories leak three points, falling from 39 per cent to 36 per cent since September, while Labour remained on 40 per cent.

But there was some backing for Mrs May in the ComRes poll, with almost half (47 per cent) of those polled saying she should remain as Prime Minister at least until Britain leaves the European Union on March 29 next year.
