DUP minister Edwin Poots has told Brandon Lewis to "bring it on" after the Secretary of State warned he would cut MLA pay if Stormont is not restored.
Mr Poots said docking MLA wages would have "no bearing" on the DUP refusing to resume power-sharing in protest over the Northern Ireland Protocol.
The Agriculture Minister also said the "future looks bleak" if the UK government's proposed legislation is not introduced to override parts of the Brexit deal on Irish Sea trade.
