1978 Lambeth Central by-election

The 1978 Lambeth Central by-election was held on 20 April 1978, following the death of Labour Party Member of Parliament for Lambeth Central Marcus Lipton.

While the seat had seen significant Labour majorities at the February and October 1974 UK general elections, and Lambeth in general was regarded as a safe Labour area, the party was struggling in the polls. They selected John Tilley, the leader of Wandsworth Borough Council who had unsuccessfully contested Kensington in the 1974 elections.

Labour's weak position gave the Conservative Party hope that it might gain the seat in a surprise victory. They stood Jeremy Hanley, a chartered accountant educated at Rugby School. The Liberal Party had little base in the area, but decided to contest the seat regardless.

Several minor parties hoped to do well in the by-election. The far right National Front had polled well in recent elections in London and maintained a high profile during the election campaign. Meanwhile, several far left groups organised in the area stood in the hope of combating the National Front and raising their own profiles. Actor Corin Redgrave stood for the Workers Revolutionary Party, while the Socialist Unity coalition and Socialist Party of Great Britain also stood, while the Socialist Workers Party stood in the name of their publication Flame - Black Workers Paper For Self Defence.

In total, eleven candidates stood, setting a new record for a by-election in the UK, one more than in the 1977 City of London and Westminster South by-election. This record was again broken at the 1981 Croydon North West by-election.
