Dominic Grieve has been criticised after meeting prominent Remainers on Wednesday night, hours before the Government was due to table its new Withdrawal Bill amendment.

The Tory rebel was seen entering the European Commission's London headquarters to attend a private meeting of campaigners intent on blocking Brexit.

The meeting included Alastair Campbell, Tony Blair's old spin doctor, a number of Remain-supporting peers and representatives from Best For Britain, the anti-Brexit group backed by George Soros.

Jacob Rees-Mogg warned Grieve that he was "supping with the Devil" by meeting with the pro-European campaigners.

The meeting took place at the Smith Square EU building in Westminster. Previously Margaret Thatcher's base, that was sold to the EU in 2007 and renamed Europa House.

The agenda was titled 'Where Next for Brexit?', according to the Daily Mail, which said the group aims to connect "the main operational UK pro-EU organisations and individuals and meets under the Chatham House Rule".
