Adele and Ed Sheeran might have more number ones and Daniel Radcliffe and Robert Pattinson may have topped the box office but when it comes to the wealth they all look up at one man: Hugh Grosvenor.

He might not be as famous as One Direction or Premier League footballers, but the 26-year-old Duke of Westminster is richer than them all with an estimated fortune of £9.2bn ($11.94bn). According to the annual Sunday Times Rich List, he is the richest under-30 in England and the ninth richest person in the UK.
