Britain’s Prince Charles is facing more questions over his charities after a newspaper reported that one of his funds accepted a 1 million-pound ($1.2 million) donation from relatives of Osama bin Laden.

Royal accounts show the British monarchy’s publicly-funded spending rose by 17% to 102.4 million pounds ($124 million) in the past year, with the renovation of Buckingham Palace taking up a large part of the expenses.

Prince Charles’ office has denied there was any wrongdoing in the heir to the British throne accepting bags full of cash as charity donations from a Qatari politician.
