The DUP’s Maurice Devenney is to stand down as a member of the Northern Ireland Assembly.
The Donegal-born politician says he wants to be able to concentrate on a number of local issues.
“This is best achieved by being based in Londonderry,” he said in a statement.
The former Mayor of Derry replaced William Hay as the party’s MLA for Foyle only five months ago.
He says he will continue in his role as a member of the new Derry & Strabane Council and will “play an active role in the party.”
DUP leader Peter Robinson thanked Mr. Devenney for his service in the Assembly.
“I have enjoyed working with him,” he said. “He has always put the interests of the people he represents to the fore.”
It’s understood the DUP will appoint Mr Devenney’s successor in due course.
