Great Britain's Jason Kenny has won his fifth Olympic gold medal with victory in the men's sprint final.
Team GB were guaranteed gold and silver after Kenny was joined in the final by Callum Skinner, both of whom were part of the victorious men's team sprint earlier this week.
Kenny powered to victory in the first race of the best-of-three series, and then held off Skinner from the front to take the gold in straight sets.
The victory puts Kenny on a par with Sir Bradley Wiggins and Sir Steve Redgrave in the list of most golds for Team GB, with Sir Chris Hoy the only man to have won more.
The 28-year-old, who won silver in the sprint in Beijing before winning gold in London four years later, successfully defends his title to move third on the list of Britain's most decorated Olympians, with the opportunity of a sixth gold coming in the keiren on Tuesday.
Russia's Denis Dmitriev claimed the bronze medal, also only needing two races to see off Australian challenger Matthew Glaetzer.
