The Member of Parliament for Kensington and Chelsea, The Rt. Hon Alan Clark (Conservative), died of a brain tumour on 5 September 1999. This was the first safe Conservative seat to have a by-election in the 1997–2001 UK Parliament. There was immediate speculation that Michael Portillo, the most high-profile casualty of the 1997 general election, would use it to return to frontline politics. Portillo immediately confirmed his interest in the seat, but was then confronted with the publication of an interview he had given previously that summer in which he had confirmed that while at Peterhouse, Cambridge he had had homosexual affairs.
