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 the half-total of the winning candidate and in an election when the pre-World War II Labour Party's vote was slightly split by the presence of a prominent Communist Party candidate and editor, Johnny Campbell, the government's ceasing of prosecution of whom in 1924 led to a General Election.
