The Democratic Unionist Party will still get £1billion for Northern Ireland despite a vow to ‘fight dirty’ against Theresa May, it has emerged.

The DUP, which has a voting pact with the Government, is deeply unhappy with Mrs May’s Brexit deal.

DUP MP Jim Shannon has vowed to fight dirty to block Theresa May's Brexit plan

MP Jim Shannon told Northern Ireland Secretary Karen Bradley at a Commons committee meeting that ministers had not shown the same ‘honour’ as the DUP over Brexit.

He added: ‘I’m going to fight quite dirty. Why do you feel the need to pursue something that is so against the … agreement we have with your party?’
