Anheuser-Busch will "have no choice" but to accept a bid from InBev if the rumours of a $65 per share offer are true, said City analysts.

Rob Mann, analyst at London-based Collins Stewart Brokers, said the offer, which values the business at $46bn, was the highest the brewer was likely to get for a long time. "A-B has been a miserable performer for five years and if InBev makes a formal offer at this level shareholders will have no choice," he said.

Another industry source told The Grocer the bid was "more than likely to go through" as although the Busch family were divided over the bid they only controlled 4% of the company.
