Usain Bolt became the first man to retain both Olympic sprint titles as he led home a gold and green Jamaica clean sweep in the 200m.
Bolt matched Michael Johnson's then world-record time from the Atlanta Games of 19.32 seconds as he held off training partner Yohan Blake in silver and Warren Weir in bronze.
"This is what I wanted and I got it. I'm very proud of myself," the 25-year-old said. Big congrats to him.
