1983–1997 The seat was created under the Third Periodic Review of constituencies in 1983, which followed the first Boundary Commission Review in 1945, which in turn directly followed the
Representation of the People Act 1918 review. It was based largely on
Paddington but also took in the abolished
St Marylebone constituency. ;Political history The seat was held with modest majorities for the first creation, made up of three terms, by
John Wheeler, a
Conservative.
Paddington constituency, its main predecessor was often
marginal: by length of a single party's representation and by majorities achieved. The far less contributory precursor,
St Marylebone, was a Conservative
safe seat. The 1997 boundary changes expanded the constituency to the west, taking in Labour-voting areas of north Kensington and tilting the seat towards Labour. Wheeler decided that he did not wish to contest such unfavourable territory and sought selection elsewhere. However he was unsuccessful in finding a new safe seat and thus retired at the 1997 general election.
2010-2024 ;Political history The seat was tipped in mainstream newspapers to be likely to achieve the necessary notional swing based on the same area's votes in the previous election, in 2005, to fall to the
Conservative candidate; however the seat fell short of the national average swing and was accordingly won by
Karen Buck. The 2015 result gave the seat the 21st most marginal majority of Labour's 232 seats by percentage of majority. In the
2017 general election,
Karen Buck increased her majority over Lindsey Hall, the
Conservative Party candidate, from 1,977 to 11,512. ==Boundaries==
