One of Margaret Thatcher's most famous lines occurred in response to speculation as to whether she would make an about-turn on her anti-inflationary policies. "To those waiting with bated breath for that favourite media catchphrase, the U-turn," she said, "I have only one thing to say: You turn if you want to. The lady's not for turning!"
She was alluding, of course, to Christopher Fry's play The Lady's Not for Burning, quite a hit in its day, as was Fry himself. The self-centered grousing of John Osborne's Jimmy Porter and the like drove lyrical optimists like Fry out of the theater.
Fry died on Thursday last. Here is an obituary in the Daily Telgraph and another in the Times of London.
