Seamus Close

Seamus Anthony Close OBE (born 12 August 1947) is a Northern Irish politician, former member of the Northern Ireland Assembly for Lagan Valley and a former deputy leader of the Alliance Party.

In August 1981 he was the Alliance candidate for the second Fermanagh and South Tyrone by-election. The following year under the redistribution and expansion of Northern Ireland's constituencies his local political base became part of the new Lagan Valley constituency which he has contested in the Alliance interest in all elections since 1983 apart from the 1986 by-election called in protest against the Anglo-Irish Agreement when the local Alliance branch declined to contest the seat as they believed the by-election was a political stunt.

Close also held several positions in the Alliance, including serving as Chair between 1981 and 1982 and as Deputy Leader from 1991 until 2001. He was often a member of the key Alliance delegations in successive talks about the future of the province, culminating in the Belfast Agreement of 1998.
