Boundary Changes: Loses Glenavy to South Antrim and Dunmurry and part of Derryaghy ward to West Belfast. The spliting of a council ward is unique in boundary reviews and came after the residents of the protestant southern part of Derryaghy expressed fears for their safety if they fell under the Sinn Fein stronghold of West Belfast.

Profile: The booming suburbs south-west of Belfast. This seat is mostly affluent and middle-class, particularly around Lisburn – the largest town – though even there there remain a few old estates where there is higher deprivation. The seat is four-fifths protestest, and the minority catholic population are evenly spread. With the removal of Glenavy and Lagmore there are no more Catholic heartlands here. The seat returns 3 DUP, 1 UUP, 1 SF and 1 Alliance to the Northern Ireland Assembly.
