Talking in his small London office a stone's throw from the Savoy, Bishop characterises his working life as a series of three-year battles against entrenched interests such as governments, the former BOAC, its successor, British Airways, and now a combination of BA and Sir Richard Branson's Virgin Atlantic. 'I have won two great battles for liberalisation and I am now on my third,' he says. 'I have not yet won it, but things look as if they are going my way.'
