Constituency profile
The seat is a mixture of very suburban London and urban district centres with many differing heights and types of homes. It stretches along the north bank of the Thames and then to the west, encompassing the London districts (former villages) of Chiswick, most of Hounslow, Isleworth (from Old Isleworth to Osterley) and the former market town of Brentford.
The seat is affluent nearest the Thames and
About three wards make up Hounslow in the west, and two for Brentford in the centre, which, excluding its expensive Quay and North Quarter parts, have an above-average rank in the
The Liberal Democrats (including their two predecessor parties) took their largest share of the vote here in 2010, but they have lacked local councillors, and the party received less than a quarter of the vote in what was essentially a three-candidate race.
The Green Party kept its deposits in three of the four contests before 2017. In the election that year it chose not to field a candidate, in order to help Labour defend its 400-vote majority.

- Political history (summary)
From 1979 until 2015, the seat proved to be a national bellwether. The 2015 result gave the seat the 4th most marginal majority of Labour's 232 seats by percentage of majority.[6] During the seat's existence, the two largest parties nationally have jostled for the winning candidate. In 2015, Labour gained the seat, despite the Conservatives winning a majority nationally, thus ending its streak as a bellwether constituency.
Split of votes in local council elections
In 2010, council seats split evenly (15—15) between the two main parties, reflecting the result of the general election held on the same day, in which the parliamentary seat was narrowly gained by the Conservatives. From 1998 to 2001, three wards at the centre of the constituency returned Independent Community Group councillors, reaching seven seats at their peak. These wards were taken by Labour in 2010.
Labour added Hounslow South in 2014, and took one of the three Osterley and Spring Grove seats, leaving them with 19 seats and the Conservatives with 11. In 2018, Labour gained the remaining Conservative seats in Osterley and Spring Grove, which gave Labour 21 seats to the Conservatives on 9.
