Matt Walls secured Britain’s first cycling gold medal of the Tokyo Olympics – and Team GB’s 50th medal of the Games overall – in the men’s omnium on Thursday.

Pole-vaulter Holly Bradshaw bagged a bronze to take the tally to 51 – equalling the mark set by Team GB at the 2008 Games in Beijing.

Earlier in the day, Dina Asher-Smith made a dramatic return to the Games as Britain’s women’s 4×100 metres relay team set a national record to qualify for Friday’s final.

Canoe sprint star Liam Heath claimed bronze in the men’s K1 200m category, while flyweight boxer Galal Yafai is guaranteed at least a silver in the men’s flyweight final on Saturday.

Jack Carlin progressed to the semi-finals of the men’s sprint but Jason Kenny’s golden reign in the event – stretching back to London 2012 – is over after he was eliminated at the quarter-final stage.

Here, the PA news agency breaks down everything you need to know about Thursday’s action.
