London South Inner was a constituency electing one Member of the European Parliament (MEP) by the first-past-the-post system. It was created in 1979 and abolished in 1999 when it was replaced by the multi-member London Constituency, using a system of proportional representation.
European constituencies were formed by the grouping of UK Parliamentary (Westminster) constituencies.
United Kingdom Parliamentary constituencies were redrawn in 1983 and the European constituencies were altered in 1984 to reflect this. The revised seat comprised the following Westminster constituencies: Dulwich, Lewisham Deptford, Lewisham East, Lewisham West, Norwood, Peckham, Southwark and Bermondsey, Streatham and Vauxhall. The same boundaries were used in 1989 and 1994. 
The seat consisted of parts of south Inner London and was a safe Labour Party seat, held by Richard Balfe throughout its existence. In 2002 Balfe was expelled from the Labour Party and joined the Conservative Party.
