Sportingbet jumped a further 8p to an all-time high of 180 1/2p amid whispers that Hilton Group (2 3/4p off at 258 3/4p) - which owns Britain's biggest bookmaker Ladbrokes - has made a tentative bid approach. Dealers heard that it would prefer a 'friendly' deal but it is prepared to go hostile if necessary. A cash offer in the region of £807m, or 250p per share, could be on the cards.
