Rio Olympics 2016: Great Britain's Mo Farah wins 5,000m & 10,000m 'double double'

Great Britain's Mo Farah won his fourth Olympic gold as he became only the second man to retain the 5,000m and 10,000m titles.

The 33-year-old triumphed in the 5,000m final in Rio to extend his tally as Britain's most successful Olympic track and field athlete of all time.
Farah won in 13 minutes 3.30 seconds as Scot Andrew Butchart finished sixth.
"It shows I didn't just fluke it in London. To do it again is incredible. I can't believe it," said Farah.
Farah's was Britain's 27th gold in Rio and their 65th medal, matching the haul at the 2012 Games in London.
They surpassed that 2012 tally when the women's 4x400m relay team won bronze in the penultimate track event of the 2016 Games.
