Swimmer Michael Phelps is now the Olympic games’s most successful ever athlete.

(Having won yet another gold in the men’s 200m freestyle relay at the Olympics in London 2012, the US swimmer from Baltimore, America, is now the proud owner of 15 gold, two silver and two bronze medals, and he still has three races to come! The bookies are giving odds-on for him to finish his Olympic career with 22 medals, and if I gambled I would take that bet.)
