Sue Lawley's castaway this week is Sir Peter Bonfield. The chief executive of British Telecommunications, it is said that when he left his previous company, its Japanese owner presented him with a samurai sword and helmet to remind him of the warrior qualities he would need at BT. And certainly the challenges facing him in this fast moving industry have tested all his discipline and determination - qualities he says he learnt as a boy at the local convent school.
