David Davies (politician)

Under-fire Cameron admits close relative suffers heroin addiction

The 39-year-old favourite in the Tory leadership race, who has been dogged by questions about whether he has used soft or hard drugs, also came under further pressure yesterday to clear the air about any personal experiences with drugs. David Davis, his nearest rival in the Tory race, raised the stakes by saying that he did not believe someone who had taken Class A drugs should become the party's leader or Prime Minister. "It's a breach of the law so if it was recent, the answer would be no," he told tonight's Morgan and Platell programme on Channel 4.
