Three Labour MPs have been accused of offering to influence government policy for cash, following secret filming by Channel 4's Dispatches programme and The Sunday Times.
Stephen Byers, Geoff Hoon and Patricia Hewitt are said to have quoted four-figure sums as repayment for their lobbying work.
Mr Byers told an investigative reporter that he had secured secret deals with ministers, could get confidential information from Number 10 and was able to help firms involved in price fixing get around the law.
All three MPs deny any wrongdoing. Laura Kuenssberg reports.
