Jeffrey Donaldson: One of the key speakers at the young Unionists conference

There is, as yet, no formal motion for the council but it is clear the delegates will be asked to pull their ministers out of the executive in the absence of IRA decommissioning and what they see as further concessions on policing.

Mr Donaldson said: "I would like to see this week clear of the kind of sniping and in fighting that there has been.

"I hope that over the next week we can have a mature and reasoned debate."

Earlier at the conference, the Ulster Unionist deputy leader said his party must decide on a "clear and specific timetable" to exclude Sinn Fein from the Northern Ireland Executive.

John Taylor told the conference there were clear provisions in the Good Friday agreement to exclude Sinn Fein if the IRA fails to decommission.

William Ross: Call for return to 'no guns, no government'

Mr Taylor said: "Many never believed that the IRA would decommission, but it had been important to expose that to the wider world."

"The Ulster Unionist Party must now decide upon a clear and specific timetable to bring about a review of the Belfast Agreement and the exclusion of Sinn Fein/IRA from the executive."

The Ulster Young Unionist Council is the largest youth organisation attached to any Northern Ireland political party and is represented at every level within the party's decision-making structures.

The party's William Ross told the conference that there had to be a swift return to the party's policy of "No guns, no government" to keep pressure on republicans to comply with their side of the Good Friday Agreement bargain.

Meanwhile the chairman of the Northern Ireland Parades Commission told the conference there should be a greater acceptance of what he called "the parading culture" in Northern Ireland.

Tony Holland said that could only happen if things change. Mr Holland said the commission could not solve the problem of contentious parades and that ordinary people had to play their part in finding a resolution.

Future of devolution

And he said he recognised that residents groups often had "deeply disturbing" experiences of loyal order attitudes and behaviour.

This body was established in 1997 to determine whether conditions, or restrictions, should be placed on contentious parades in Northern Ireland.

On Friday, Mr Taylor predicted that the Northern Ireland Executive would collapse by Christmas unless there was a start to IRA decommissioning.

The Strangford MP gave his pessimistic assessment about the future of devolution, as US President Bill Clinton called on politicians not to give up on the Good Friday Agreement.

On Friday, Sinn Fein's Alex Maskey said the IRA had "not broken any of its promises".

Meanwhile, the SDLP's Mark Durkan has said he believed the assembly would survive in spite of unionist claims that it could collapse by Christmas.

Mr Durkan who's the finance minister at Stormont, told BBC NI's Inside Politics programme on Saturday, he expected David Trimble to be supported by his party's ruling council next week despite growing unionist concerns on decommissioning.
