Sixty Conservative MPs are to launch a plan to take down Theresa May's Chequers deal this weekend, with series of reports setting out how a 'clean' Brexit will work.

The plans will argue for a free trade agreement, and present solutions to the Northern Irish question and vexed issues like farming and agriculture.

One source told The Telegraph that the plans – running to over 100 pages – will seek to deal once and for all with the Northern Irish issue to offer a solution to unlock the talks.

The 60 MPs in the European Research Group, led by Jacob Rees-Mogg, want to neutralise the European Union's criticism that ensuring there is no hard border with Northern Ireland means Britain must stay closely tied to the EU.

The papers will be released over four days starting from Sunday.

The BBC reported today that the papers will address money and migration on Monday, followed by a key paper on Northern Ireland on Wednesday.
