SIR – If Sam Gardner, another dyed in the wool republican who has crept out of the woodwork, thinks he can persuade right-minded people to become republicans he is on a hiding to nothing, especially when he says the Duchess of Cambridge’s unborn child might not have the right disposition to be our head of state (T&A, July 6).

Recent polls show that the majority of people approve of the royals, so in an attempt to make them change their minds he composes a letter full of fatuous garbage. Big mistake.

That said I am at a loss to understand why Mr Gardner still resides in this country.
