ULSTER Unionist Party (UUP) ministers threatened to resign from Northern Ireland’s power-sharing executive yesterday over claims that the Provisional IRA is still active.

The Police Service of Northern Ireland (PSNI) and largest Stormont party the DUP have both claimed that the IRA was behind the killing of dissident republican Kevin McGuigan two weeks ago.

The claims were based on speculation that Mr McGuigan was responsible for the shooting of former IRA commander Gerard “Jock” Davison three months ago.
