PARTY TIME: Clive Sinclair and Jeffrey Archer

Legendary inventor and computer genius Sir Clive Sinclair was a friend of many years standing of John Swinfield. They met up again at a party given by the Tory peer and novelist Jeffrey Archer and his wife Mary at their Grantchester home in Cambridge. John recalls a colourful cast including Lord Archer, who went to jail for perjury; Michael Edwardes, the cost-cutting boss of stricken car conglomerate British Leyland, and the fruity-voiced thespian Donald Sinden. 
With Oxford and London, Cambridge is in a high-tech golden triangle – and the recipient of an £850 million pound infrastructure investment by Blackstone, one of America’s most powerful investment firms.
