A fresh round of all-party talks aimed at saving the power sharing executive is due to begin in the North this morning.
Last week, First Minister Peter Robinson stood aside along with three other Democratic Unionist Party ministers.
It followed the arrest of three leading republicans - including Sinn Féin's northern chairman Bobby Storey - as part of the investigation into the murder of Kevin McGuigan.
The PSNI has linked the murder to the IRA.
Sinn Féin has blamed the crisis at Stormont on a row between the DUP and the Ulster Unionist Party.
But Acting First Minister - the DUP's Arlene Foster - says this is nothing to do with an election.
