Historyedit
Summary of winning results
The 2015 result made the seat the 44th-safest of Labour's 232 seats by percentage of majority.[3] Successive candidates fielded by the Labour Party have won absolute majorities (pluralities) since the seat was created in 1918, or have run unopposed four times. The 2019 election was the first time in the seat's 101-year history that Labour failed to win an absolute majority, though the party still won with a margin of 22%
Opposition parties
Four parties have taken the runner-up position from and including a 2002 by-election, a total of five elections. At the 2015 general election the Liberal Democrat, Green and TUSC candidates did not win 5% of the vote apiece therefore forfeited their deposits. Those running for the Conservatives and UKIP in 2015 (and 2016 at the by-election held during the month before the UK's EU membership referendum) held their deposits. The highest polling of any runner-up, by percentage, was Thomas George Jones in 1931, winning 30.8% of the votes cast, 0.3% more than half the percentage polled by the winning candidate; this was when the Labour Party's vote was slightly split by the presence of a prominent Communist Party candidate and editor, Johnny Campbell. The government's dropping of a prosecution against him in 1924 had led to a General Election.
Turnout
Turnout at general elections has ranged between 85.3% in 1950 and 57.8% in 2005, falling to 35.2% in the 2002 by-election.
