Boris Johnson’s right-hand man has topped a list of the world’s worst-dressed men.

Dominic Cummings, the Prime Minister’s top political adviser, is well-known for sporting a blue and navy quilted gilet.

Cummings’s love of sports hoodies, jeans and fleece vests was also noted by GQ, which compiled the list.
