Tesco chair to leave after claims over behaviour

John Allan is stepping down as chairman of Tesco following allegations over his conduct.

Mr Allan, who is also a former president of the CBI business lobby group, has strongly denied three of four claims made against him.

However, Byron Grote, who will temporarily replace Mr Allan as chair, said: "These allegations risk becoming a distraction to Tesco."

Tesco said it made "no findings of wrongdoing".
