Andy Murray has won an historic second Olympic title after defeating Juan Martin Del Potro in the men's singles final.
Murray, 29, beat the Argentinian 7-5 4-6 6-2 7-5 in a tense final in front of a rowdy crowd.
He has become the first player to win two Olympic singles gold medals after defending his London 2012 title.
Murray - who this year has become a father for the first time, won his second Wimbledon title and led Team GB out at the opening ceremony - was visibly emotional at the end of the match.
He won Britain's fifth gold on day nine in Rio to cap off a hugely successful day.
"It means a lot," said Murray, his eyes red from tears.
"Getting to carry the flag at the opening ceremony was an amazing experience and I was very honoured. I found that quite emotional," he added.
"I had to regroup and get my mind on the matches so, to finish it with a match like that, obviously I was fairly emotional at the end. It's been a build-up of emotions over the last 10 days and (I'm) just very happy that I got over the line tonight.
"It was one of the hardest matches I've had to play for a big title. The US Open I played with Novak to win my first slam was very hard but tonight I found really difficult emotionally. Physically it was hard, there were so many ups and downs in the match."
