Ulster Unionist Coalition Party [SEP] inception
Ulster Unionist Coalition Party
The Ulster Unionist Coalition Party (UUCP) was a minor unionist political formation in Northern Ireland. 
Following a split in the Democratic Unionist Party (DUP) majority bloc in Ballymena in 2007, six councillors who objected to the DUP's agreement to share power in the Northern Ireland Executive with Sinn Féin left the DUP and redesignated themselves as the "Ulster Unionist Coalition Party". In May 2009, four of the group left to join Jim Allister's Traditional Unionist Voice (TUV).
