East Belfast was once an assured DUP stronghold but the party's dominance in the constituency has been gradually chipped away amid a growing Alliance vote.
Taking in areas including Ballymacarrett and Dundonald, the constituency for years was the fiefdom of former DUP leader and ex-First Minister Peter Robinson.
But in perhaps a sign of changing times, this year the local DUP association had no say in choosing their election candidates - because of not having enough paid-up members.
