Olympics Rio 2016: Vintage Phelps wins 19th Gold

The record books have been re-written in the swimming pool with the American Michael Phelps winning his 19th Olympic gold medal with a stunning performance, having quit the sport after the 2012 Olympics.

Earlier on Monday, British swimmer Adam Peaty won Britain's first medal of the games with gold. But in tennis the Murray brothers were knocked out of the doubles in the first round.
