The former Speaker of the Northern Ireland Assembly Lord Alderdice now sits in the House of Lords as a Liberal Democrat peer, although formally represents the Alliance Party, the Northern Irish sister party of the Lib Dems.
The Alliance Party was formed in 1970 to provide an alternative to parties organised on sectarian grounds.
It currently has one MP and eight members at Stormont, and its current leader, David Ford, is the Justice Minister in the Northern Ireland Executive.

The former presiding officer of the Scottish Parliament, Lord Steel, now sits as a Liberal Democrat member of the House of Lords.
He was presiding officer from 1999-2003, the first person to hold the post.
Lord Steel was previously a Liberal, subsequently Liberal Democrat, MP and was the last leader of the Liberal Party before its merger with the SDP in 1988.
