Complaints that the SDLP and UUP leaderships have carved up Assembly posts for colleagues continued yesterday at Stormont.
Mr David Ervine, of the PUP, was critical of the fact that only two members from the smaller parties would be allowed to sit on the 17-member committee of the centre set up to scrutinise aspects of the work of the First and Deputy First Ministers.
"When I make my arguments I make them on the basis of the Good Friday agreement - the sense of inclusion that was meant to be in it and the degree of consultation that inclusion requires."
In the chamber yesterday, the Alliance party leader, Mr Sean Neeson, urged that the chairman of the public accounts committee be appointed from a party other than the four parties in the Executive.
However, the first nomination to posts of chairmen to the Assembly statutory committees was made by Mr David Trimble, who appointed Mr Billy Bell (UUP, Lagan Valley) to the public accounts committee.
The Alliance chief whip, Mr David Ford, described the UUP leader's actions as incredible.
In a statement, the Northern Ireland Women's Coalition said the arrogance of the SDLP and the UUP was "breathtaking".
The Coalition was critical of Mr Trimble and Mr Seamus Mallon's amendment which passed during a late sitting of the chamber on Tuesday and established a limited committee of the centre to oversee the work of the central office.
