Martin Gilbert, the former vice-chair and co-chief executive of Standard Life Aberdeen, says Donald Trump’s US election success in 2016 is a feat unlikely to be repeated again by another non-political figure running for the White House.

Gilbert, who is now chair of digital bank Revolut, attended Trump's inauguration in Washington after meeting the soon-to-be former US president in Aberdeen. Trump owns a golf course there and the two share a passion for the sport.
