The date for the Welsh assembly by-election in Blaenau Gwent caused by the death of Peter Law has been announced as 29 June.
A double by-election is being held in Blaenau Gwent
Mr Law, who died last month aged 58, was independent MP and AM for the south Wales valleys seat.
His death has caused Wales' first double by-election.
It is expected that the parliamentary by-election will be held on the same day, with an official announcement likely soon from the Commons.
Several parties contesting the assembly by-election have already selected their candidates.
The Conservatives have picked Cardiff councillor Jon Burns to contest the seat while John Hopkins will stand for the Labour Party.
The Liberal Democrats have chosen Abertillery councillor Steve Bard and Plaid Cymru is due to confirm its candidate next Monday.
The Blaenau Gwent People's Voice group, which backed Mr Law, is expected to endorse a candidate who will stand as an independent.
