(Wards renamed and redrawn before 2010 election.) Summary of boundary review The Fifth Periodic Review of Westminster constituencies by the Boundary Commission for England was implemented nationally in 2010. Parts of Highgate, Gospel Oak, Haverstock, and Camden Town with Primrose Hill wards were transferred from the former constituency of Hampstead and Highgate. The electorate of the new seat would have been 85,188 if it had existed in that form at the 2005 general election. The electorate has since risen further, and at the 2010 general election it was among the five highest electorates in London. Members of Parliament The seat was held from 1983 to 2015 by Frank Dobson of the Labour Party, who had been elected in 1979 to the predecessor seat of Holborn & St Pancras South. Dobson was the longest-serving Labour MP in London until he stood down in 2015. The constituency has been represented by Keir Starmer since the 2015 general election, who has served as Leader of the Labour Party and Leader of the Opposition since April 2020.
