John Bercow, MP for Buckingham, has confirmed he will be voting in the EU referendum – but he is keeping his cards close to his chest.
As Commons Speaker, Mr Bercow does not get involved in national issues like the in/out debate.
But he will be joining his Buckingham constituents in marking a card on June 23 to decide whether Britain should remain in the union.
Mr Bercow said: “I will not be campaigning in the run up to the referendum on the UK’s membership of the European Union. I intend to exercise my right to vote in the same way as everybody else on the Electoral Register will be able to do.
“This question will be answered by the British public as a whole – not by individuals. I encourage all of my constituents living in the Buckingham constituency to have their say on June 23.”
David Cameron - along with Labour and the Lib Dems - wants Britain to stay in the EU. But about half of Tory MPs, including five cabinet ministers, several Labour MPs, UKIP and the DUP are all in favour of leaving.
