Record-breaking Michael Phelps extended his tally to 21 Olympic gold medals as he won individual and team titles on day four at Rio 2016.
The American, 31, comprehensively beat defending champion Chad le Clos in the 200m butterfly.
The most decorated Olympian of all time then helped the US win the men’s 4x200m freestyle relay by a wide margin.
British quartet Stephen Milne, Duncan Scott, Dan Wallace and James Guy won the silver medal.
Phelps has won more than twice as many Olympic gold medals as the athlete second on the list, former Soviet gymnast Larisa Latynina (nine).
