In the 1980s I commissioned the late Denis Healey to write a piece - and take the photographs - for the Sunday Mirror about a trip he was to take in South Africa. The negotiations over deadline and content were conducted by his ‘secretary’ who had a suspiciously vaudevillian falsetto. It dawned on me eventually that it was the great man himself who perhaps wanted to keep his distance from the sordid business of negotiating a fee (£1,000). He wrote a very perceptive piece on apartheid with pictures to match.
