Northern Ireland's Deputy First Minister, Martin McGuinness, has stepped down as the MP for Mid-Ulster.
He will remain a member of the MLA.
He said the move was in line with his party's commitment to end double jobbing.
Mr McGuinness was elected MP for Mid-Ulster in 1997, but he has never taken his seat in Westminster.
A by-election is expected to be held in the New Year.
