Harry and Meghan have cost taxpayers £44 million since their wedding, according to a new book.
The cost of their accommodation, security and staff has been examined by author Norman Baker, a former Lib Dem MP.
He has written a book called …And What Do You Do?, analysing the costs to the public purse of the royal couple.
The pair – who quit royal life to live in America with their son Archie – celebrated their second anniversary on May 19 and the bill for their wedding alone came to £33.5m, of which the royals contributed £2m.
Mr Baker calculated that their security cost £7m, including £4.5m for the months they lived at Frogmore Cottage in Windsor.
He said: “From their wedding day to March 31 this year, I estimate the British taxpayer has forked out almost £44m to provide Harry and Meghan with, it seems, whatever they want.
“We were promised that public funding for the pair would end after March 31, when they officially stepped back from royal life.
“But things are not that simple. Even though they have left our shores, there’s still a hefty bill to be paid.”
