The ruling body of the Ulster Unionist Party has voted to withdraw from Northern Ireland's power-sharing government.

The decision follows claims by the PSNI that members of the Provisional IRA were involved in the murder of Kevin McGuigan.

According to the BBC, Leader Mike Nesbitt said the party will withdraw Danny Kennedy, its only executive minister, and called the executive a 'busted flush.'

Following the murder of McGuigan, PSNI Chief Constable George Hamilton said that the infrastructure of the IRA remains, though the killing was not sanctioned by the hierarchy.

Sinn Féin leader Gerry Adams vehemently denied that the IRA still exists, however Nesbitt said the republican party had "no credibility and we have no trust and without trust we have nothing."
