Two-time Olympic taekwondo champion Jade Jones suffered a shock first-round defeat by Kimia Alizadeh of the Refugee Olympic Team in Tokyo.
Jones was aiming to become the first British woman to win Olympic golds at three consecutive Games, but those hopes were ended by a 16-12 loss.
Alizadeh, who won bronze at Rio 2016, was later beaten in her semi-final with Tatiana Minina.
That result also ended Jones' hopes of a bronze via the repechage.
The loss to Alizadeh is a hugely disappointing outcome for Jones, who looked stunned when defeat was confirmed having gone into the Games as one of Britain's favourites to secure a medal.
Alizadeh had beaten Jones twice before, including at the World Championships in 2015, but it looked as though Jones would live up to her favourite tag as she won the the first round 6-4.
But Alizadeh took the next two 6-2 6-4 to secure the victory.
Alizadeh made history when she competed in taekwondo at the Rio Olympics in 2016.
Aged only 18, she beat Sweden's Nikita Glasnovic 5-1 in the bout for the bronze in the -57kg category. It made her the first Iranian woman to win an Olympic medal.
But in the wake of that success she felt Iran's authorities were using her as a propaganda tool and fled her home country in January 2020.
