The first minister of Northern Ireland has announced talks about the potential exclusion of Sinn Fein from the Northern Ireland Assembly.
Peter Robinson's statement comes after police said they think the Provisional IRA may be involved in the murder of former IRA member Kevin McGuigan in Belfast last week.
Sinn Fein's Gerry Kelly says the paramilitary organisation is not to blame - but instead a criminal gang calling itself "Action Against Drugs".
