A portrait of former First Minister David Trimble could soon be hanging on the walls of Stormont.
David Trimble left the UUP to join the Conservatives
The Assembly Commission has agreed in principle to pursue the matter.
A portrait of the SDLP's Seamus Mallon, the former deputy first minister, is already in the member's dining room.
The commission is expected to write to Lord Trimble about having the portrait.
The former NI first minister joined the Conservative Party earlier this year.
Lord Trimble, who led the Ulster Unionists for 10 years from 1995, said the move was part of a "long-term ambition".
Lord Trimble won a Nobel Peace Prize, along with the SDLP's John Hume, for his part in the 1998 Good Friday Agreement.
However, he stepped down as leader of the Ulster Unionist Party, after losing his Westminster seat in Upper Bann in the 2005 general election.
