The Socialist Green Unity Coalition is an electoral alliance formed by leftist parties and political organisations in Great Britain prior to 2005 parliamentary election. After the 2005 election the coalition continued to operate as a liaison and co-ordinating body but has not extended its remit much beyond electoral co-ordination. It was established after the Respect Unity Coalition (which the SGUC constituent organisations regard as little more than a vehicle for the Socialist Workers Party) rejected requests to discuss an electoral arrangement to avoid clashes in 2005 (despite the fact that Respect had offered such an arrangement to the non-socialist Green Party).
