Theresa May is facing a fresh headache as Europhiles on her backbenches gang up to seize control of Brexit.

Pro-Remain Tories were last night accused of plotting to re-write parliamentary rules to put them in the driving seat if the Prime Minister is defeated in the Commons tomorrow.

Former Attorney General Dominic Grieve will today team up with Liberal Democrat leader Sir Vince Cable to publish draft legislation revealing how they could push for a second referendum.

Meanwhile, former Tory ministers Sir Oliver Letwin and Nick Boles will host a meeting of like-minded MPs to plan how they will block a 'no-deal' Brexit.

It comes after 20 Tory MPs last week helped inflict a humiliating defeat on the Government over Brexit after Commons Speaker John Bercow tore up parliamentary convention.

As Britain prepares for a tumultuous week in politics, Andrew Pierce profiles the plotters-in-chief and the MPs conspiring to stop a hard Brexit.

Conservative MP Anna Soubry speaks at a Peoples Vote anti-Brexit rally at Victoria Hall, Sheffield on Saturday

Shockingly abused by Right-wing thugs last week outside Parliament who called her a 'Nazi'.

Increasingly detached from the Government with pro-Europe views with which she tours TV and radio studios.

Comprehensive school-educated, studied law and was a TV presenter before going into politics. Quit the Tories in 1983 to join the SDP but then rejoined the party when it was led by Eurosceptic Iain Duncan Smith.

Other gaffes include saying he'd rather 'beg on the streets' than send his two children to state schools.

Tasked with implementing the Leveson inquiry into Press standards, he cooked up a deal which would have introduced statutory regulation of newspapers for the first time in centuries.

The former Education Secretary has been a persistent thorn in the side of Mrs May who sacked her in her first Cabinet reshuffle.

She later apologised but was exposed for hypocrisy when photographed herself with a £950 Mulberry handbag.

The Oxford-educated solicitor considered standing as party leader in 2016 but humiliatingly got only a handful of MPs to back her. Still rankles over her demotion from Cabinet.

Faced calls to resign after his family car was seen to have a window sticker saying 'b******s to Brexit, it's not a done deal'
