Lobbyists will be regulated and voters will get the power to sack their MPs after the latest sleaze scandal to hit Parliament in Britain.
Following media disclosures about MPs and peers taking money from undercover reporters posing as lobbyists, Deputy Prime Minister Nick Clegg has pledged to bring in laws to create a "cleaner, better politics".
Clegg said the lobbying scandal - which has involved asking questions and influencing debates about Fiji - has again shown that Britain's "political system has long been crying out for head-to-toe reform".
His comments came as a peer, Lord Laird, resigned from the Ulster Unionist Party.
MP Patrick Mercer has already quit the Tory party following an investigation by the Daily Telegraph and BBC's Panorama that revealed he tabled parliamentary questions and motions and offered lobbyists a security pass to the House of Commons after being paid thousands of pounds.
