MP Tim Yeo facing committee coaching claim
A senior MP, who chairs parliament's Energy and Climate Change Committee, is alleged to have used his position to help a private company influence Parliament.
Sunday Times investigators secretly filmed the Conservative Tim Yeo, who is a former environment minister.
He told them he coached the boss of a firm - owned by a company that was paying the MP - on how to give evidence to the committee, the paper alleges.
Mr Yeo denies that, and says he intends to contest all the allegations.
BBC News understands that he has referred himself to the Parliamentary standards commissioner.
