The area has elected Labour MPs since its creation in 1945, on strong majorities of over 20% of the vote, except for the results in 1983, 1987 and 1992.
Margaret Hodge served as the MP for the seat from 1994 to 2024. The rise in support for the
British National Party since the turn of the 21st century saw the party attain 16.9% of the vote at the
2005 general election, with the Labour vote reduced by over 13% compared to the 2001. The BNP out-polled the Liberal Democrats for third place and were just 27 votes behind the Conservatives. Party members and supporters were optimistic that the party would soon make a breakthrough into the UK parliament, and party leader
Nick Griffin stood in Barking for the
2010 general election. However, his performance in Barking was poor, as he polled 14.6% of the vote (representing a decline in percentage terms compared to 2005), and Margaret Hodge retained the seat with 54.3% of the vote, doubling her majority. The Conservatives came second with 17.8%. During the run-up to the 2010 election, filmmaker Laura Fairrie had access to the British National Party and Labour Party campaigns, and later produced a documentary
The Battle for Barking, which premiered on
More 4 on 30 November 2010. In 2015, the
UKIP vote increased to almost 23%; this was predicted as they came the runners up in every ward in the 2014
Barking and Dagenham Council election, they came within 200 votes of winning 4 seats on the council. In 2017, the UKIP vote collapsed, and Labour and the Conservatives both increased their share of the vote, although Labour's increase of 10.1% saw them claim 67.8% of the vote overall (their largest share in Barking at any election since the
1994 by-election and the greatest at a general election since
1970), increasing their majority from 35.5% to 45.3%. Despite a swing away from Labour in the 2019 election, its majority was still a healthy 34.7%. Following Margaret Hodge's retirement as an MP, Labour's vote at the
2024 general election fell by 16.5%; however its majority only fell by 4.4% as the Conservative vote collapsed to 11.8%. Both
Reform UK (14.2%) and the
Green Party (13.7%) overtook the Conservatives, relegating them to fourth place. The
Workers Party candidate took 9.8% of the vote. == Boundaries ==
