Ian Paisley, the suspended MP for North Antrim, has said he would have resigned if he had thought he had done anything to warrant it.
The Democratic Unionist Party (DUP) man was suspended from the House of Commons after failing to declare holidays paid for by the Sri Lankan government.
He could lose his role as an MP if 10% of his constituents sign a petition. "If I believed that I'd done anything that deserved me to resign from my job I would not be there today," he said.
Mr Paisley has also been suspended by his party while it investigates his conduct. Voters in his constituency have been signing a recall ballot, which opened this month, calling for him to face a by-election.
Speaking to the BBC's Talkback, he said he had "been very quiet" about his suspension since he made a statement about it at Westminster last month. "I've let that stand - I have accepted the report from the House of Commons and apologised for it."
