SIR – Thanks to the diligent work of pressure group Republic, the Royal Household has at last been called before a House of Commons select committee to account for their shameful expenditure.

For too long, the millionaire Windsor family have been given a free hand to fritter away taxpayers’ cash, while ordinary people struggle with stagnant wages and the rising cost of living.

Not surprisingly, Mrs Windsor once again escapes criticism in the media. In no other institution would the person at the top remain completely blameless. The Diamond Queen? Perhaps “The Teflon Queen” would be more appropriate.
