JACOB Rees Mogg has told Brexiteers to trust Boris Johnson to broker a deal with Brussels but warned to expect compromise.
Mr Rees Mogg said that concessions with EU chiefs were inevitable but the PM could be trusted to deliver.
The House of Commons leader said the mood was more positive after Mr Johnsons successful showdown with Irish PM Leo Varadkar last week.
Boris will hope to win the support of EU bosses for his deal at a crucial summit on Thursday.
The meeting is seen as his final chance to get a withdrawal agreement over the line ahead of the Brexit deadline of October 31.
Arch-Brexiteer Mr Rees Mogg wrote in The Telegraph: In the final stages of the Brexit negotiation, compromise will inevitably be needed, something even the staunchest Leavers recognise albeit unwillingly – but as a Leaver Boris can be trusted.
“He wants to take back control and has dedicated his political career to this noble cause. If he thinks the ship of state is worth an extra ha’porth of tar he deserves support.”
His comments came as the DUP fired a warning shot to the Prime Minister over a reported compromise to end the deadlock over the Northern Ireland backstop.
Deputy leader Nigel Dodds warned the mooted plan “cannot work”.
This is a blow for Mr Johnson as he needs the support of the DUP to get his deal through Parliament.
It is believed the plan is currently being discussed by EU and UK officials in Brussels in the wake of Mr Johnson’s secret meeting last week with Mr Varadkar in Cheshire.
Reports from the Belgian capital claimed the PM had sought to revive a proposal first put forward by Theresa May for a customs partnership between the UK and the EU.
The scheme, intended to avoid the need for customs controls on the island of Ireland, would see Northern Ireland remain politically in a customs union with the EU but it would be administered by the UK.
However Mr Dodds told the Italian La Repubblica newspaper that Northern Ireland “must stay in a full UK customs union, full stop”.
“It cannot work because Northern Ireland has to remain fully part of the UK customs union,” he said.
He added: “There is a lot of stuff coming from Brussels, pushed by the Europeans in the last hours, but one thing is sure: Northern Ireland must remain fully part of the UK customs union. And Boris Johnson knows it very well.”
