The price tag was revealed in an annual report, but one anti-monarchy advocate speculates the true cost could be even higher.

The coronation of King Charles III and Queen Camilla held in May last year cost British taxpayers £72 million ($91 million), an amount some have labeled excessive.

The astronomical number, paid by the U.K. taxpayers during a cost-of-living crisis, isn’t winning over many royal fans. Graham Smith, Charles’ most vocal critic, and CEO of the anti-monarchy group Republic, wasn’t exactly thrilled about the final tally. He described the spending of taxpayers’ money as “obscene” to The Guardian.
