Business Diary: Lion's share goes to wrong man

Our compliments to David Buik, the BGC Partners commentator who has been doing such sterling work defending the bankers and their bonuses in recent days. Still, yesterday's blog didn't quite make sense. Entitled "Bob Diamond – Androcles in the lion's den, I don't think so", Buik forecast there would only be one winner in the battle between Bob Diamond and the Treasury Select Committee: the Barclays man. But the point of the famous tale is that Androcles was the winner – he was pardoned in the gladiatorial arena after a lion which he had once cared for refused to attack him. Time to spend a bit of that City pay packet on a decent book of fables.
