The Meanings of Conservatism

'We're witnessing a major change in British politics,' writes John Gray. 'But to what?' With Boris Johnson on the way out, many Conservatives, he says, believe the party needs a new 'big idea'. But that is a fundamental error, he believes. 'What the party needs is not another new philosophy but a healthy dose of pragmatism...new thinking, but not some grand new theory'.Producer: Adele Armstrong Sound: Peter Bosher Production coordinator: Gemma Ashman Editor: Penny Murphy
