Clarence House said Prince Charles received charitable donations and the correct processes were followed regarding those donations after a British newspaper reported the Prince of Wales once accepted a suitcase containing €1 million ($1.05 million) in cash from a Qatari politician.

According to the Sunday Times, the suitcase containing €1 million in cash was one of three lots of cash he personally received, totaling €3 million, from former Qatari Prime Minister Sheikh Hamad bin Jassim bin Jaber Al Thani between 2011 and 2015. CNN has not independently verified The Sunday Times report.

"Charitable donations received from Sheikh Hamad bin Jassim were passed immediately to one of the Prince's charities who carried out the appropriate governance and have assured us that all the correct processes were followed," Clarence House told CNN in a statement.

The Sunday Times reported on one occasion, Sheikh Hamad gave Prince Charles €1 million reportedly stuffed into carrier bags from the upmarket London department store, Fortnum and Mason.
