Tokyo Olympics: Chelsie Giles wins Team GB's first medal of Games for judo after Jade Jones's shock taekwondo defeat

Team GB has won its first Olympic medal of the Tokyo Games after Chelsie Giles got bronze in the judo.

Giles, 24, from Coventry, won the repechage against Switzerland's Fabienne Kocher in the -52kg category on Sunday.

She was given a shot at third place after losing to Japan's Uta Abe in the quarter final.

It came after huge disappointment for Team GB with taekwondo's Jade Jones suffering a shock defeat in the first round.

Jones, 28, was hoping to become the first British woman in history to win three golds at three consecutive Games.

But despite a two-point lead in the beginning, Kimia Alizadeh of the Refugee Team beat her 16-12 in the first bout.

Commenting on the result, Jones said: "I'm absolutely gutted. It's not how I planned the day to go and just really frustrated with myself, I wasn't the best today so I just have to take it on the chin and congratulate the other girl."

She added that the lack of spectators and family support was a "struggle".

Alizadeh represented Iran at the Rio Games in 2016, becoming the country's first female athlete to get an Olympic medal after securing bronze behind Jones.

The double Olympic champion lost out on a chance at bronze in the repechage when Alizadeh lost in the semi-finals.

Dreams of a Team GB taekwondo gold were kept alive by Bradly Sinden, however.

The 22-year-old from Doncaster won three rounds, beating Tom Burns of New Zealand, Hakan Recber of Turkey and Zhao Shuai of China to reach the 68kg final.

Elsewhere, there were celebrations for Tunisia after 18-year-old swimmer Ahmed Hafnaoui stunned by winning gold for the Men's 400m Freestyle. He is the second Tunisian ever to get an Olympic gold.

But there was more disappointment for Team GB when Sir Andy Murray announced he was pulling out of the Men's Singles due to a thigh strain.

He was due to play world number nine Felix Auger-Aliassime of Canada on Sunday, but was replaced by Australian Max Purcell.

Murray had been hoping for his third consecutive Singles gold, but will now only play in the Doubles with partner Joe Salisbury.

He said: "I am really disappointed at having to withdraw but the medical staff have advised me against playing in both events, so I have made the difficult decision to withdraw from the singles and focus on playing doubles with Joe."

There was better news for Team GB swimmer Adam Peaty who powered through to the 100m breaststroke final with the fastest time on Sunday morning.

The 26-year-old world and Olympic champion won his semi-final comfortably in 57.63 seconds, slower than the 57.56 in Saturday's evening heats but more than a second quicker than China's Yan Zibei. American Michael Andrew was third in that heat, 1.36 off Peaty's time.

While way off his world record 56.88, it meant he now has the top 16 fastest swims of all time in the event.

Peaty made a point of bowing when he appeared poolside despite the lack of spectators.

"It's obviously very different to the worldwide perspective," he said.

"When you're actually here, everyone's so welcoming and so happy. These are the Olympic Games, they are the greatest show on earth and obviously we want to show our mutual respect."

It comes as officials confirmed there had been 11 more confirmed new coronavirus infections, including three athletes, at Tokyo 2020, taking the total number of cases to 138 since 1 July.

On Sunday morning, world number one golfer Jon Rahm of Spain tested positive for the second time in less than two months. He had to withdraw from a tournament in Ohio in June due to COVID and is now out of the Games.

American golfer Bryson DeChambeau also tested positive and will be replaced in the US men's golf team by Patrick Reed, USA Golf said.

DeChambeau said: "I am deeply disappointed not to be able to compete in the Olympics for Team USA.

"Representing my country means the world to me and it is was a tremendous honour to make this team. I wish Team USA the best of luck next week in Tokyo.

"I will now focus on getting healthy, and I look forward to returning to competition once I am cleared to do so."

Also, the International Olympic Committee has confirmed there will be no relaxation on mask-wearing rules.

Spokesman Mark Adams said: "It's not a 'nice to have', it's a 'must to have'."

He was responding to a question about several swimmers removing their masks during medal ceremonies.

The Olympic teams from Kyrgyzstan and Tajikistan were also mostly maskless when they paraded through the stadium at Friday's opening ceremony, despite other national teams covering their faces in according with COVID-19 rules.
