I refer the hon. Member to the written answer I gave the hon. Member for Brentwood and Ongar (Mr. Pickles) on 24 October 2006, Official Report, column 1775W, in relation to the timetable for laying the draft Order to give effect to the new English constituencies.
The subsequent timing of debates on the draft Order and the making of the Order in Council are matters for the Parliamentary Business Managers and the Privy Council respectively.
Once the Order is made, it does not take effect until the next general election thereafter.
