Lynch (50), who has been described as "Europe's Bill Gates", has an Irish passport. His mother was from Tipperary and his father from Cork. He built up the Autonomy software company after raising £2,000 from "an eccentric" in a pub, he told the Sunday Independent last year.
Later he sold Autonomy to HP for €10bn, in Europe's largest ever software company sale. It sparked a vicious row and lawsuit with HP, after the US firm wrote down the value of the acquisition and claimed it had been sold a pup. Lynch disagrees. The lawyers are at each other's throats.
Since then he raised €1bn to invest in cutting-edge tech, ranging from cyber security to artificial intelligence. Lynch has a stately pile in Suffolk and owns a 1965 Aston Martin DB5, like the one featured in the James Bond film Goldfinger.
