BREXIT battles are set to ramp up yet again - as Nigel Farage prepares a tour of Britain trying to push a No Deal scenario.

The ex-Ukip leader is teaming up with other senior Brexiteers and holding a series of high-profile rallies designed to put pressure on Theresa May.

And the PM is also being squeezed on the other side as calls grow for a second referendum which could keep us in the EU.

Mr Farage is leading the push to convince ministers they should ditch the proposals agreed at Chequers - and instead adopt a No Deal approach where we trade with the EU on World Trade Organisation terms.

He is headlining at least six rallies over the next few weeks, visiting towns including Bolton, Torquay and Gateshead with the Leave Means Leave group.

The former Ukip boss will speak alongside senior Tories such as David Davis and Jacob Rees-Mogg, as well as Labour figures including Vauxhall MP Kate Hoey.

In a direct challenge to Mrs May, one rally will take place in Birmingham on the same day the Tory party conference starts in the same city.

Businessman Richard Tice said today: “Leave Means Leave will be travelling across the country to make the case that the Prime Minister should chuck the Chequers plan and save £39billion by adopting a World Trade Deal.”

The group is also placing adverts in local newspapers pushing for a WTO Brexit.

In a separate headache for the PM, London Mayor Sadiq Khan today became the latest senior figure to back a second EU referendum.

He told the BBC’s Andrew Marr Show: “I’ve thought long and hard about this. The reality is this, we’ve now reached a position where there are two outcomes - a bad deal, or No Deal.

“What needs to happen is this - we defer leaving the European Union to allow the British public to have a say on the outcome of negotiations.”

Mr Khan hinted that Jeremy Corbyn had tried to talk him out of the move.

Lib Dem deputy leader Jo Swinson said: “I think it shows that momentum is building to have a people's vote on the deal."

But Labour’s Barry Gardiner, a close ally of Mr Corbyn, claimed a second referendum would be a boost for Mrs May because it would reduce the pressure on her to unite her MPs behind her own Brexit plan.

He said: "Calling for a second referendum is really giving her a lifeline because then she can say 'Oh, if I can't get it through Parliament I'll go back to the people'."
