The DUP's Iris Robinson has been suspended from Stormont for a day after refusing to withdraw comments she made about the health minister.
Iris Robinson faces a 24-hour suspension from the chamber
Speaker Willie Hay, also a DUP MLA, ruled that her remarks about Michael McGimpsey were "unparliamentary".
Earlier this month, Mrs Robinson accused Mr McGimpsey of misleading the assembly over the draft budget.
"I cannot withdraw it, will not withdraw it, because it was the truth I was trying to establish," she said.
Mr Hay said he wasn't "somebody that fudges issues".
"Let me make it absolutely clear, irrespective of what side of the house it comes from, I will deal with issues no matter how difficult those issues are," he added.
'Lacking the bottle'
During the controversial debate at the start of November, Mrs Robinson, chair of health committee, accused Mr McGimpsey of "lacking the bottle to make decisions".
She launched the attack after the UUP minister said, because of cuts in his budget, people in Northern Ireland were far worse off in health care than the rest of the UK.
Mr McGimpsey said he had only agreed the draft budget as a basis for consultation.
He said he took exception to Mrs Robinson's accusations and that there was a period of consultation currently being undertaken.
