MP Patrick Mercer 'offered Commons security pass'
Labour has called on the government to introduce an official register of lobbying firms following the resignation of the MP Patrick Mercer from the Conservative Party, over lobbying allegations.
The Daily Telegraph has alleged that he agreed to offer a Commons security pass to a fake firm that paid him £4,000 to table parliamentary questions.
Mr Mercer said he took the money for consultancy work outside Parliament. He is taking legal advice and has referred himself to Parliament's standards commissioner.
