TUV leader Jim Allister has claimed recent events have shown the Northern Ireland executive to be a "catastrophic" political failure.
The North Antrim MLA addressed around 200 party members gathered in Templepatrick, Co Antrim on Saturday. The party leader said that a recent monitoring report confirming the existence of the Provisional IRA army council had "comprehensively vindicated and validated the TUV analysis and position".
He said the recent deal reached by the DUP, Sinn Féin and British and Irish governments was "a series of climbdowns".
"What a catastrophic failure DUP-Sinn Féin misrule has been", he said.
"Little wonder Sinn Féin MLAs gave Peter Robinson a standing ovation. Didn't he let them keep their Army Council in government?
"Of course they gave him a standing ovation. They have reason to be grateful to him. What a legacy for the man who once said the only cabinet the IRA should be in is one with brass handles".
He added the TUV would lay out a "positive vision" in next year's assembly election.
Guest speaker, Labour MP Kate Hoey, told party members that leaving the EU "is not just a view of right-wing people, on the left there is a really strong argument for leaving.".
The MP for Vauxhall, who was born in Northern Ireland ,said she was "genuinely pleased" when invited to the conference, adding that while she did not agree with Jim Allister on everything she had "great admiration for him as a conviction politician who spoke out even when in a great minority".
The party announced 11 candidates selected so far for next year's assembly election, including Henry Reilly formerly of Ukip who was expelled from the party after a disagreement with party leader David McNarry.
Mr Reilly, from Kilkeel in Co Down, was Ukip's candidate in last year's European elections, in which he received more than 24,000 votes.
The party has yet to confirm if Ruth Patterson, expelled from the DUP last week for making comments about party colleague Emma Pengelly, will stand as a TUV candidate in south Belfast. It is believed the Belfast city councillor has been in contact with the TUV about a possible move.
