When it published its annual accounts the Windsor family again claimed that it costs the taxpayers only £37m a year. Republic, the group that campaigns for the abolition of the feudal institution, put the true figure at closer to £152m. This includes police protection and tax breaks for family members. It does not include their income from the duchies of Cornwall and Lancaster.
Forty four MPs have signed a motion calling greater transparency in the accounts of the Duchy of Cornwall, which provides Charles Windsor with £14m annually.
