Dagenham and Rainham is aparliamentary constituency[n 1] inGreater London that was created in 2010. It has been represented in theHouse of Commons of the United Kingdom since2024 byMargaret Mullane and was previously represented from2010 byJon Cruddas, both members of theLabour Party.
The constituency may retain significant pockets of poverty indicated by a high ranking in theIndex of Multiple Deprivation compiled in the year 2000 however average incomes were in four large wards close to the national average.[2] TheLondon Borough of Barking and Dagenham saw the most rapid decrease in people of White British ethnicity in the 10 years to the 2011 census, of 31.4 percentage points. However the same dataset shows that 58.3% of people are white in the seat, which is similar to theGreater London average. An established area of settlement for British people of Asian ethnicity with 15.9% of this background, the neighbouringLondon Borough of Newham has a much higher proportion of residents with Asian heritage, 43.5%.[3]
Before 1945 the Dagenham area was part ofthe Romford constituency. The MP for the latter seat since 1935, Labour'sJohn Parker, continued to represent Dagenham until 1983. Parker was the last serving MP to have been elected before the Second World War, and with 48 years in Parliament, was the longest-serving Labour MP in history, a record he held until December 2017. The seat was first contested in the2010 general election which resulted from theBoundary Commission's report that recommended merging the majority of the former constituencies ofDagenham andHornchurch and added to existingelectoral wards a small part of River ward was also transferred fromBarking.
In 2010 Labour'sJon Cruddas took the seat gaining amarginal 5.9% win, facing a strong nominal (ward-by-ward) Lab–Conswing measured against the previous forerunner seats and candidates.BNP candidate Michael Barnbrook came third with 11.2% of the vote, his party's second-best showing in the election. In 2015, Cruddas, incumbent won an 11.6% majority; the runner-up party changed to beingUKIP closely followed by the Conservative candidate.
In 2019, Cruddas' majority was cut to just 293 votes, the lowest Labour majority in Dagenham ever, which has been represented by Labour MPs since 1945.
The electoral wards in both boroughs were redrawn in 2022 and subsequently the constituency no longer aligns with ward boundaries.
