The seat was created in 1983, replacing the former constituency ofCarshalton, which had voted Conservative at every election since its creation in1945. The new Carshalton and Wallington initially followed suit as a safe Conservative seat, being won by the party by a wide margin (ranging from 18.8% to 28.7%) at each of the first three general elections of its existence.
However, the large national swing against theConservatives in 1997 saw the seat gained by theLiberal DemocratTom Brake by a decisive margin of 11.2%.
Brake would hold the seat for the next 22 years, being one of just eight Liberal Democrat MPs to survive the party's near-wipeout at the2015 United Kingdom general election - Carshalton and Wallington was one of just two seats in the southern half of England, the other beingNorth Norfolk to be retained by the party that year.
After narrowly holding on to the seat for the Liberal Democrats in both 2015 and 2017, Brake was defeated by the ConservativeElliot Colburn by just 629 votes at the2019. Brake had been the party spokesman onBrexit. The Liberal Democrats fiercely campaigned against Brexit; however, this seat voted to leave in the2016 referendum.
The Liberal Democrats regained the seat at the2024 general election by a margin of 16.9% – their largest ever majority in the constituency.
Demographically this zone of London has littlesocial housing and much of the housing, overwhelmingly semi-detached or detached, is to some extent considered to be in thestockbroker belt; some of the south of the seat has fine views from the slopes of theDowns and many small parks and recreation grounds characterise the district.
