Vodafone, which has just collected an £84 billion windfall from the sale of its 45 per cent stake in Verizon Wireless of the US, is either a hero or an anti-hero of British capitalism, according to taste. To me, the world’s second-largest mobile phone business is heroic because it achieved that position from a standing start just 30 years ago, when poker-playing Ernie Harrison, chief executive of a military radio manufacturer called Racal, bet everything he had on the future of mobile telephony.
