The leader of the Ulster Unionist Party has called for an end to the system of mandatory coalition at Stormont.
The system ensures that every party with significant representation is offered a seat at the executive table.
Speaking at his party's conference this afternoon, Doug Beattie said it was time to change and allow for a "working opposition".
"A mandatory five-party coalition no longer delivers good government," he told delegates.
The change to a system of government and opposition would allow the electorate to "vote out those not up to the role and vote in those with a better vision for the future", he said.
Mr Beattie said the Good Friday Agreement, which established the political institutions in Northern Ireland 23 years ago, was long overdue change.
He said a system had developed that had seen political vetoes used to frustrate change.
"Stormont has become dysfunctional and people are angry."
Mr Beattie, a former soldier who once guarded former Nazi leader Rudolf Hess in Spandau Prison, said his brand of unionism was confident and inclusive.
