SIR - Not content with volunteering for an arduous year in the Army, Prince William, above, is about to train as a pilot, then do a spell in the Navy.

Between times he is fulfilling royal duties like meeting patients and staff evacuated from the blaze-hit Royal Marsden Hospital (T&A, January 5), the very place where he worked for two days in 2005 for charity.

One day, if all goes well, he will be our King, and rightly so.

Walter Bagehot, the 19th century essayist and economist said: "The only fit material for a constitutional king is a prince who in his youth is superior to pleasure and who in his youth is willing to labour."

Such a prince is William.
