Labour Co-ordinating Committee
The Labour Co-ordinating Committee (LCC) was a faction in the British Labour Party, established in 1978 and wound-up in 1998. It moved from a group established to challenge the leadership of the party from the left to the vanguard of Tony Blair's drive to modernise the party's organisation and policies.
