He was the Guv'nor. The self-styled hardest man in Britain. For years, Lenny McLean was known as the UK's most fearsome bareknuckle boxer, undefeated in some 3,000 fights. In later life he began a new career as an actor, with a defining role in Lock, Stock and Two Smoking Barrels. Now it's his alter ego, Grant Thornton chief executive officer Michael Cleary, who's calling the tune. Cleary's standing on the door, guarding the way for private equity investment into his firm. If your name's not on the list, you ain't comin' in. Got it?
