Under the Sixth Periodic Review of Westminster constituencies, the Coalition government planned to review and redraw the parliamentary constituency boundaries for the House of Commons of the United Kingdom. The review and redistricting was to be carried out by the four UK boundary commissions to produce a reduction from 650 to 600 seats, and more uniform sizes, such that a constituency was to have no fewer than 70,583 and no more than 80,473 electors. The process was intended to address historic malapportionment, and be complete by 2015. Preliminary reports suggesting the areas set to lose the fewest seats historically tended to vote Conservative, while other less populous and deindustrialized regions, such as Wales, which would lose a larger proportion of its seats, tending to have more Labour and Liberal Democrat voters, partially correcting the existing malapportionment. An opposition (Labour) motion to suspend the review until after the next general election was tabled in the House of Lords and a vote called in the United Kingdom House of Commons, in January 2013. The motion was passed with the help of the Liberal Democrats, going back on an election pledge. , a new review is in progress and a draft of the new boundaries has been published.
