The party's 'Vote Labour Everywhere' strategy was changed in 2000 to support Ken Livingstone for London Mayor and this ultimately led to the biggest purge in the party's history. A vote at the central committee with a one-vote majority led to nine expulsions from the party of those opposed to the Livingstone decision for factionalism, and some subsequent resignations, including nine members of the central committee. The North West District was dissolved and altogether around 25 members were either expelled for factionalism or resigned from the party.
