The Parliamentary Constituencies Bill: no fewer MPs but a very different constituency map

Pontefract_Parliamentary_Borough_1832A new bill currently before parliament alters the rules governing the periodic redrawing of the UK’s parliamentary constituencies, most notably by replacing a requirement to limit the House of Commons to 600 MPs with a new fixed size, set at the current 650. But, as Ron Johnston, David Rossiter and Charles Pattie show, the new rules are just as likely as those they replace to result in major disruption to the constituency map at all future reviews. 

In 2011, the coalition government passed the Parliamentary Voting System and Constituencies Act, which changed the rules guiding how the UK’s parliamentary constituencies are drawn up. Boundary reviews were to take place every five years (more frequently than before). Almost all new seats (with four exceptions) were to have electorates within +/-5% of the national quota (the average electorate). And the House of Commons was to be reduced in size from 650 to 600 MPs. To date, the Boundary Commissions have conducted two redistricting exercises under the 2011 Act. Neither review has been implemented: the first was lost to infighting in the coalition, and the second was tabled in September 2018 but has not yet been approved by parliament. The proposed changes they contained would have produced the largest shake-up in Britain’s constituency map in modern times.

Now the redistricting rules look set to change again. The Parliamentary Constituencies Bill 2019-21, published on 20 May, is now moving through its Committee Stage in parliament. It retains the requirements that all constituencies (with four exceptions) should have an electorate within +/-5% of the national average, but changes the number of constituencies to 650 – the argument being that with Brexit there will be more work for MPs, and thus a need for more of them, than if we had remained a member of the EU. If the Bill is passed, the Boundary Commissions will be required to recommend a new set of 650 constituencies by 1 July 2023 – in time for the next general election, due in May 2024. Subsequent reviews will then take place on a slightly longer timetable than under the 2011 Act – every eight years. Continue reading

The Parliamentary Constituencies Bill: how to ensure a level playing field

alan.jfif (1)professor_hazell_2000x2500_1.jpgLegislation now before parliament will reform how parliamentary constituencies are drawn up. Most controversial is a proposal that the recommendations of the independent boundary commissions should be implemented automatically. Alan Renwick and Robert Hazell argue that the principle of automatic implementation is right, but it should be combined with stronger safeguards on the commissions’ independence. 

The government’s Parliamentary Constituencies Bill was debated in the House of Commons for the first time earlier this week. The bill, if passed, will keep the number of MPs at 650, cancelling a cut to 600 that was legislated for in 2011 but has not yet been implemented. It will also alter the procedures for drawing up Westminster constituency boundaries, in four main ways. First, it will reduce the frequency with which boundaries are reviewed, from five- to eight-year intervals. Second, it will slightly shorten the duration of the next review (but only the next one), from 34 to 31 months, to ensure its conclusions can be implemented in good time for a 2024 election. Third, it will adjust the sequence of the review process, so that public hearings on proposed boundaries take place after an initial round of written submissions. Finally, and most importantly, it will make the implementation of new boundaries automatic: parliament will lose its current power to block the proposed changes.

Cancelling the cut in the number of MPs is no longer controversial. That reduction was introduced in 2011 in the wake of the MPs’ expenses scandal, when public scepticism about the value of MPs’ work was at a peak. It was designed to show that ministers understood people’s anger about perceived waste at the heart of politics. Since then, however, parliament has done much to reassert its value. MPs have become more independent-minded in holding government to account. Following reforms implemented in 2010 – some of which were strongly based in earlier Constitution Unit research – select committees have risen greatly in prominence, and are now widely seen as doing much important work. Furthermore, many constituents were discomfited when they saw that cutting the number of MPs would reduce their own local representation at Westminster. The cross-party support that exists for retaining 650 MPs is therefore welcome.

Some of the changes to review procedures have, however, proved more contentious. In particular, opposition parties have argued against the introduction of automatic review implementation. Speaking in the Commons on Tuesday, both the Shadow Minister for Voter Engagement, Cat Smith, and SNP Spokesperson David Linden called it ‘a power grab’ by the executive over the legislature. Labour’s Stephen Kinnock described it as ‘nothing short of a constitutional outrage’. Continue reading
