Jacob Rees-Mogg has said his Brexiteer Tory organisation ERG will unveil an alternative plan for Northern Ireland today.
The group has faced criticism from opponents who say it has attacked the Government's plans without coming up with one of its own on one of the main sticking point in discussions between Brussels and the UK.

Speaking at an Economists for Free Trade event yesterday, Mr Rees-Mogg said people could "come along and you will discover what our solution is to the Northern Ireland problem, which is the only thing that is obstructing" a free trade agreement dubbed Canada-plus with the EU.
He added: "It is possible to move very swiftly to a Canada- plus style deal as long as we can come up with a scheme, which I think we have got for tomorrow, on how you ensure a solution to the Northern Ireland problem that any reasonable person would accept."
At the same event, former Foreign Secretary Boris Johnson warned Theresa May's Chequers plan for a Brexit deal "turns us into a vassal state'."
Mr Johnson said that by accepting single market legislation, Chequers risks making it "substantially worse than the status quo" for British businesses.
