Jason Kenny has clinched his fifth Olympic gold medal after beating Team GB teammate Callum Skinner in the men's sprint final.
London 2012 champion Kenny sealed victory in straight rides in the best-of three final, drawing him level once again with Sir Bradley Wiggins with five golds. He can take his tally to six and equal Sir Chris Hoy's record when he competes in the keirin final next week.
Kenny and Skinner were part of the three-man team that won Team GB's first cycling medal of Rio 2016 alongside Philip Hindes, beating New Zealand to clinch gold in the team sprint event last Friday (12 August).
Great Britain was guaranteed both gold and silver in the individual event, and Kenny drew first blood in their first race after a rapid overtake on the final bend, breaking free down the back straight.
Skinner needed to win the second race to keep the contest alive but again his teammate overpowered him to take the victory.
Elsewhere, Russia's Denis Dmitriev secured the bronze medal in straight rides against Australia's Matthew Glaetzer.
Great Britain have been dominant in indoor cycling events in Rio. After Kenny, Skinner and Hindes got the ball rolling in the men's team inidivudal sprint, both the men and women's teams secured gold in team pursuit events, each shattering world records in the process.
Becky James also picked up a silver medal after her hugely impressive performance in the women's keirin final.
Kenny's latest triumph takes Great Britain's gold count up to 14 following Max Whitlock's triumphs in two gynmastics events on Sunday evening and Justin Rose's success in the golf event.
