Sir: Edward Heath is not the only former premier to whom a nautical simile has been applied ("After 46 years in Parliament, `old Dreadnought' sets sail for one more battle with the young guns", 1 February). Gladstone, referring to Peel, said that "former prime ministers are like great rafts floating untethered in a harbour".
There are many who think that every harbour needs elderly vessels, whether seaworthy or derelict. They are picturesque, lend dignity and keep pilots alert.
