Swimming superstar Adam Peaty won Great Britain's first gold medal of the Tokyo Olympics and triathlete Alex Yee secured a silver as day three began in memorable fashion.

It doubled Britain's medal haul following successes for Bradly Sinden and Chelsie Giles in taekwondo and judo on Sunday.

Peaty had been a red-hot favourite to win the 100 metres breaststroke, and he duly delivered, making history by becoming the first British swimmer to retain an Olympic title.

And Yee continued Britain's run of success in Olympic triathlon with a silver medal on debut.

Here, the PA news agency takes a look at today's action so far, and Britain's further prospects.

What's happened so far today?

At the age of just 23, Yee confirmed his world-class quality, finishing second behind Norway's Kristian Blummenfelt. Reflecting on a podium finish, he said: "It doesn't feel quite real that it's me yet." Yee's performance set the stage for Peaty to do what he does best – dominate his rivals. He stormed to victory at Tokyo Aquatics Centre in a time of 57.37 seconds, while his Team GB colleague James Wilby finished fifth. The Olympic rugby sevens tournament also began, with Great Britain's men – silver medallists in Rio five years ago – beating Canada 24-0 at Tokyo Stadium, while 13-year-old Momiji Nishiya from Japan took gold in a thrilling women's street skateboarding event.

Britain's men's rugby players face a tough clash against Japan, GB's women hockey players – gold medallists in Rio five years ago – will look to bounce back from an opening game defeat when they tackle South Africa, while Britain's men's archery team have reached the quarter-final stage.
