Usain Bolt confirmed his status as the greatest sprinter of all time as he stormed to victory in the 200m to win his 5th Olympic gold medal.

The Jamaican retained the title he won back in Beijing four years ago with a blistering display as he clocked a winning time of 19.32secs to beat his good friend Yohan Blake.

Bolt became the first man ever to retain the 200m title as Jamaica made it a clean sweep with Warren Weir who ran a personal best to claim the bronze medal.

There were plenty of celebrations between the three Jamaican's but it was hard not to feel sorry for the 22-year-old Blake who once again could only watch Bolt storm to victory.

Bolt made the perfect start and had a commanding lead coming into the home straight and was even able to ease down and celebrate as he crossed the line.

Blake was also well clear of his team-mate in third place as he ran 19.44, while Weir ran the race of his life to claim his first Olympic medal in a time of 19.84.

The time of 19.32 was the same time that Michael Johnson ran at Atlanta 1996 to take the world record and is the fourth fastest time in the history of the race.

"This is what I wanted and I got it. I am very proud of myself. I came out here and did what I had to do," said Blake.

"I thought the world record was possible. I guess I was fast but not fit enough. I could feel my back strain a little bit, so all I did was to keep my form. I'm very dedicated to my work and London meant so much to me."

Weir was also delighted with his bronze medal, saying: "It's a great honour to come here to do that and give people what they wanted. The love in London is very, very good. One love, Jamaica,"
