Cameron and Johnson
London Mayor Boris Johnson (L) and Prime Minister David Cameron (R) will go head-to-head in a bid to persuade UK voters over their stance to 'leave' and 'remain' in the EU respectively Reuters

As the UK prepares for a referendum on its membership of the EU on 23 June, MPs from a number of parties have come out in support of the "Remain" or "Leave" camp. Notably, a number of Tory MPs have defied Prime Minister David Cameron's stance to stay as part of a reformed EU and will be voting to leave the bloc.

All 54 Scottish National Party (SNP) MPs are supporting efforts to prevent a so-called Brexit while the same can be said of the three Plaid Cymru MPs. Sinn Féin has said that it will "campaign vigorously against a Brexit".

The Conservative party is experiencing open warfare over the legal status of Cameron's EU deal, with Justice Secretary Michael Gove claiming that it would not stand up under legal scrutiny and could be overruled by the European Court of Justice (ECJ).

Labour rebels backing the "Leave" camp include Kate Hoey, Kelvin Hopkins, Graham Stringer and Gisela Stuart. Meanwhile Birmingham Perry Barr MP Khalid Mahmood has left the "Leave" campaign over concerns that it "has become a single topic campaign focused on immigration".

IBTimes UK has compiled a list of MPs and their position on the EU referendum. The list is based on which camp they have directly expressed their support for either through a letter to constituents or a statement via social media.
