Prince William has been spotted selling copies of the Big Issue in London, just days after Queen Elizabeth II's Platinum Jubilee.
The Mirror reports that an eagle-eyed passer-by was stunned to meet the unassuming royal, as he did his bit for charity in Westminster.
Retired Met Police chief superintendent Matthew Gardner shared photos of William on his LinkedIn account after his brother-in-law's chance encounter with the heir to the throne in Westminster.
