Falkirk is a county constituency of the House of Commons of the Parliament of the United Kingdom. It was created for the 2005 general election, replacing Falkirk West and part of Falkirk East. At the 2015 general election, it was the seat with the largest majority for the SNP as well as the seat with the largest majority for any party in Scotland. At the 2019 general election it again had the highest numerical majority of any SNP-won seat in Scotland, although other seats, including Aberdeen North, had higher majorities in percentage terms. The constituency takes in the town of the same name and stretches west to include Denny, Stenhousemuir and Banknock. Boundaries Falkirk has been joined by most of the various sized towns and villages of its council area in this new seat, including Airth, Bainsford, Banknock, Bonnybridge, Brightons, Camelon Carronshore, Denny, Falkirk, Glen Village/Hallglen, Head of Muir, Larbert, Laurieston, Polmont, Redding, Shieldhill, Stenhousemuir, Tamfourhill, and Westquarter. A south eastern arm of the seat curls around Grangemouth. The seat sits to the south of the River Forth. History 2013 Labour selection irregularities The Labour Party leadership was embroiled in a row with the Unite the Union over the selection of a candidate to replace disgraced former Labour MP Eric Joyce. In 2013, local officials of Unite, led by Len McCluskey, were accused of abusing membership procedures by "bulk-buying" and "packing" the Falkirk Constituency Labour Party with their own members in an attempt to get their preferred candidate, Karie Murphy (Labour election chief Tom Watson's office manager), selected. Unite was alleged to have signed up and paid the subscriptions for over 100 new party members in Falkirk, some of them allegedly unaware they were joining the Labour Party. A leaked Unite document from December 2012 detailed its activity in Falkirk as "exemplary" for the way in which "we have recruited well over 100 Unite members to the party in a constituency with less than 200 members. 57 came from responses to a text message alone, (followed up face to face). A collective effort locally, but led and inspired by the potential candidate". On 25 June 2013, Falkirk CLP was placed in "special measures" by the National Executive Committee at an emergency meeting after an internal report found "sufficient evidence for concern about the legitimacy of some new recruits to the Falkirk party."
