The Socialist Green Unity Coalition was an electoral alliance formed by leftist parties and political organisations in Great Britain prior to 2005 parliamentary election[1] after the Respect Unity Coalition (which the SGUC constituent organisations regarded as little more than a vehicle for the Socialist Workers Party) rejected requests to discuss an electoral arrangement to avoid clashes in 2005.
[1] The SGUC also gave greater priority than most of its individual members to the question of the environment and building a sustainable economic system - largely due to the influence of the Alliance for Green Socialism.
The Socialist Party contested the 2005 election as Socialist Alternative in Bootle, Brighton Kemptown, Bristol North West, Cardiff South and Penarth, Coventry North East, Coventry South, Leicester West, Lewisham Deptford, Newcastle East and Wallsend, Sheffield Heeley, Stoke-on-Trent Central, Swansea West, Wakefield, Walthamstow, Wythenshawe and Sale East.
As of January 2010, the Socialist Party's continuing membership of SGUC is unclear as they have allied themselves with the TUSC (Trade Unionist and Socialist Coalition) from which other SGUC members (notably the Alliance for Green Socialism) had withdrawn.
This, and a lack of recent electoral activity, suggests that the SUGC has been dissolved.
