Lord Brian Mackenzie of Framwellgate: 'I have not broken the rules'
Three peers have been accused of agreeing to carry out Parliamentary work for payment.
Undercover Sunday Times reporters filmed the men appearing to offer to help a fake solar energy company.
Ulster Unionist Lord Laird, and Labour's Lord Mackenzie of Framwellgate and Lord Cunningham, deny wrongdoing.
The two Labour peers have been suspended from the party and Lord Laird has resigned the party whip pending an investigation.
Sir Brian Mackenzie spoke to the News Channel before he was suspended from the party. He said in that interview that he would not be resigning the Labour whip.
