In January, our Prime Minister David Cameron promised that a Conservative government would hold an in/out referendum no later than 2017.
Conservative MP for Stockton South, James Wharton, has come first in the ballot for a Private Members Bill. And James has announced that he will try to use it to put the Prime Minister's commitment into law.
So this is an opportunity for MPs to make this historic referendum on Europe a reality.
But the passage of the Bill won't be smooth. Labour and the Liberal Democrats have put up strong opposition to offering the British people their say - and that's why Conservative MPs need to offer every support they can to James and his Bill.
The vote on this Bill will be on Friday 5th July and our Chief Whip has put in place a Three Line Whip for all Conservative MPs.
Like all of our MPs, I have a busy constituency diary and I place great importance on meeting constituents every Friday.
But this week, I will be asking my Association Chairman, as I am asking you today, to understand the absence of their Member of Parliament on the 5th July while they attend this historic vote in the Commons. We will of course try to keep further Friday disruptions to a minimum, but I suggest that Chairmen are in touch with their Members of Parliament for further information and the passage of this Bill is likely to require further sitting Fridays.
I also wanted to let you know that soon we will be launching a campaign to communicate our message to the country, and put pressure on both Labour and the Lib Dems to make this referendum a reality.
As Conservatives we believe that the British people have a right to decide on our membership of the European Union, and we are determined to show that we mean business - even in the face of resistance from our political opponents.
I will continue to update you on our progress."
Grant Shapps MP
Conservative Party Chairman
