Rishi Sunak, MP for Richmond has said he wants to leave the EU and is the fifth Yorkshire MP to back the out campaign.
Mr Sunak, who was elected in May 2015, spent four days considering his decision after David Cameron returned from the EU Council with a raft of proposals for a reformed EU.
However he won’t be backing the Prime Minister in the run up to the June 23 referendum, instead
He wrote on his Facebook account this morning: “After much thought I have decided to vote for Britain to leave the EU. Now to sit down and set out to my constituents the reasons for my decision.”
The successor to William Hague - who this week warned MPs against division on the issue - is understood to have concerns about immigration as well as the economic impact of remaining in the EU.
After attending Stanford University in the USA and a successful career in business, the father-of-two moved his family to Yorkshire last year to begin his political career.
He will now write to his constituents personally to explain more about his decision and his full reasoning will be released towards the end of the week.
