The Independent Commission on the Voting System, popularly known as the Jenkins Commission after its chairman Roy Jenkins, was a commission into possible reform of the United Kingdom electoral system.
It was set up in December 1997 by the Labour government to investigate alternatives to the First-Past-the-Post system used for general elections. A referendum was planned on whether to change the voting system. The commission reported in September 1998 and suggested the Alternative vote top-up or AV+ system. No action was taken to change the electoral system. Labour's manifesto in 2001 stated:
'We will review the experience of the new systems (in Scotland, Wales and Northern Ireland) and the Jenkins report to assess whether changes might be made to the electoral system for the House of Commons. A referendum remains the right way to agree any change for Westminster'.
