Alliance Party leader David Ford is expected to announce that his party will nominate him for the justice ministry in Northern Ireland.
Sinn Féin and the Democratic Unionist Party have already agreed that they would not fill the controversial role.
Mr Ford has been the favourite for the post for when security powers are transferred from Westminster to Stormont.
The responsibilities are to be devolved by 12 April as set out under the Hillsborough Castle agreement.
Progress was announced this week on a cohesion and integration strategy demanded by the Alliance Party as part of their price for taking the justice position.
Speaking at a press conference at Stormont this morning, Mr Ford said it was agreed that the two conditions put forward by the Alliance party had been met.
Mr Ford said that the identity of the party's Justice candidate had not been decided, however he conceded that he 'was minded' to nominate himself.
Meanwhile, a parades working group of six senior DUP and Sinn Féin assembly members has reported back to the Office of the First Minister and Deputy First Minister.
This was one of the groups set up arising from the Hillsborough agreement earlier this month.
There is expected to be a public consultation on the measures this spring.
