Oaten calls in the police over leaked e-mails

There is an extraordinary story on the Guardian website tonight:

Mark Oaten's struggling campaign to lead the Liberal Democrats ran into trouble tonight after Charles Kennedy's office accused his team of leaking emails implying the former party leader was backing him.

Mr Oaten, the party's home affairs spokesman, denied he or his team had been involved and called in the police and parliamentary authorities to investigate.

But the author of one of the leaked emails, Mr Kennedy's head of office, Anna Werrin, told party chiefs that she believed "some bright spark on Mark's campaign thought it would boost his chances if it looked as though he had Charles's backing".
