Greene King share price shot up last week after rumours the brewer had received an informal approach from a potential buyer. There was speculation that financier Robert Tchenguiz, who already owns about 870 managed and tenanted pubs, could have been involved. Greene King's 2,000 pubs would fit his strategy. But neither the brewer nor Tchenguiz's R20 investment vehicle made an announcement to the Takeover Panel Another possible buyer is entrepreneur Michael Cannon, who bought Eldridge Pope in 2003. Meanwhile Tchenguiz is preparing to make a £2.7bn formal offer for Mitchells&Butlers by the May 8 deadline. But commentator Frank Kane, in The Observer, believes the odds are stacked against him.
