Commentary from Mike Costello as Usain Bolt won the men's 200m to claim his second gold medal at Rio 2016, his eighth at an Olympics.

Former British sprinter Darren Campbell praised the 29-year-old's performance: "Thank you, thank you, thank you for blessing us with your greatness."

The Jamaican ran home ahead of Canada's Andre de Grasse and France's Christophe Lemaitre.

Britain's Adam Gemili clocked the same time as Lemaitre, but was denied his first Olympic medal in a photo finish.
