Labour has called on Conservative MP Tim Yeo to stand down as chairman of the Energy and Climate Change Committee after claims that he breached lobbying rules by allegedly offering to use his position to further business interests.
Tim Yeo has the right to defend himself but it is difficult to see how he can continue as chair of the select committee pending investigation by the Parliamentary Standards Commissioner.
If David Cameron won't act then Tim Yeo should take it upon himself to stand down from his post.
Mr Yeo has denied the claims and has referred himself to the Parliamentary Standards Commissioner.
