Thirteen-year-old Sky Brown earned a momentous skateboarding bronze to become Great Britain's youngest Olympic medallist as victories in sailing and showjumping on Wednesday took Team GB's gold medal tally to 15.

Hannah Mills and Eilidh McIntyre clinched gold in the 470 class, making Mills the most successful female Olympic sailor of all time after her gold in Rio five years ago and silver at London 2012.

Ben Maher then won gold in the individual showjumping event on board Explosion W after a dramatic six-horse jump-off.

Boxer Ben Whittaker secured a men's light-heavyweight silver medal after Frazer Clarke took bronze in the men's super-heavyweight division.

With six medals guaranteed in Tokyo this is Britain's most successful Olympics in the boxing ring since 1920, when just 12 nations took part.

Meanwhile, Canada's Andre de Grasse won his first gold and fifth Olympic medal overall as he overhauled world champion Noah Lyles in the men's 200m final.
