The mandatory coalition at Stormont should end and the salaries and expenses of MLAs should be halved, UKIP leader Nigel Farage has said.
Mr Farage described the Northern Ireland Assembly as a "cosy consensus".
He was speaking at the launch of his party's assembly election manifesto in Belfast.
UKIP says Stormont is too expensive and has called for the number of MLAs to be reduced, although the party does not say by how many.
It also wants the UK to withdraw from Europe and restrict immigration to give priority to the "needs of the UK".
UKIP is standing six candidates in the assembly election.
