From BBC NEWS:
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. In a separate investigation by the BBC's Panorama programme in conjunction with the Daily Telegraph, Lord Laird was also secretly filmed discussing a retainer to ask parliamentary questions.
The House of Lords code of conduct says peers must not act as paid advocates and "must not seek to profit from membership of the House by accepting or agreeing to accept payment for providing parliamentary advice or services".
