Will the rules for the redistribution of Parliamentary constituencies be changed by the next government – as recommended by a House of Commons Committee? Or will another disruptive exercise reducing the number of MPs begin within a year of the 2015 election, as currently scheduled? As Ron Johnston, David Rossiter and Charles Pattie show, there are no clear commitments in the parties’ manifestos.
In 2010 the Conservatives were convinced (correctly) that the operation of the electoral system for the UK House of Commons was currently biased against them: they get a smaller share of the seats than Labour from the same percentage of votes cast. They were also certain that variations in constituency electorates were a major cause of this anti-Tory bias. So, meeting one of their manifesto commitments, one of the first bills introduced by the coalition government in 2010 – the Parliamentary Voting System and Constituencies Bill – proposed that for the first time all UK constituencies should have an electorate within 5 per cent of the average. It also proposed a reduction in the period between redistributions by the Boundary Commissions to every five years (fitting the timetable of the Fixed Terms Parliament Act, 2011) and changes to the nature of the public consultation procedure during those redistributions – whilst at the same time reducing the number of MPs from 650 to 600.
Commentators and the Boundary Commissions had both indicated that these changes would be very disruptive to the constituency map. This turned out to be the case when the Commissions’ provisional recommendations for new constituencies were published in late 2011-early 2012. The subsequent public consultations stimulated many alterations to that map, but merely rewrote the disruption. Many existing constituencies were dismembered, and new ones were proposed that bore little resemblance to the pattern of communities on the ground: a large number of MPs and their local parties were not very content with the likely outcome of the drive for greater equality of representation.
