The Sunday Times is reporting this was one of three cash donations from former Qatari Prime Minister Sheikh Hamad bin Jassim bin Jaber Al Thani.
Clarence House says the donations were passed onto one of the Prince’s charities, and that all correct processes were followed.
Reports suggest the money was handed over in a duffle bag at Clarence House. While, carrier bags were also used on other occasions.
It’s understood the donations took place between 2011 and 2015.
