Greyhound trainer Graham Calvert lost £2 million earlier this year during a five month gambling spree and is currently serving a two year prison sentence for possession of cocaine and firearms.

He has just lost his appeal to recover some compensation from William Hill, the betting firm through which he lost the £2M. The Chronicle Live reported: “Calvert, 28, a greyhound trainer from Houghton-le-Spring, lost the cash during a disastrous five-month betting spree.

The High Court rejected a damages action in which he claimed the firm failed in its “duty of care” by allowing him to continue betting after he asked it to stop taking his money under its “self-exclusion” policy. He challeneged this decision today but was again unsuccessful.”
