Britons Caden Cunningham and Rebecca McGowan both reached the taekwondo quarter-finals on their Olympic debuts.
Cunningham, hailed as the future of the sport by two-time GB bronze medallist Bianca Walkden, beat Nigeria’s Abdoul Issoufou 2-0 in the men’s +80kg category in Paris.
That was followed by McGowan quickly beating Fiji’s Venice Traill 2-0 in the women’s +67kg.
Cunningham faces Cuba’s Rafael Alba from 13:40 BST before McGowan takes on Svetlana Osipova of Uzbekistan at 14:45.
Great Britain have won a taekwondo medal at every Olympics since Athens in 2004, but have struggled in Paris.
Favourite Bradly Sinden had to withdraw injured before his men’s -68kg bronze medal match with injury, while two-time gold medallist Jade Jones suffered another early defeat in the women’s -57kg.
