Desperate Cameron contacted Eliasch 15 times to try to stop him defecting

So says the Sunday Telegraph:

David Cameron made a series of desperate bids to persuade Johan Eliasch, the Conservative Party's former deputy treasurer, from signing up as an adviser to Gordon Brown. It was claimed that Mr Eliasch, a millionaire businessman, was contacted as many as 15 times by Mr Cameron as the Tory leader made a vain effort to dissuade him from defecting to the Prime Minister.
