American Michael Phelps remains on course for his 22nd Olympic gold after he reached the final of the 200m individual medley at the 2016 Olympics.
Phelps, 31, who has secured three gold medals in Rio, finished ahead of fellow American Ryan Lochte to win the semi-final in one minute 55.78 seconds.
Six-time Olympic gold medallist Lochte is through along with GB’s Dan Wallace, but Briton Ieuan Lloyd missed out.
The men’s 200m individual medley final takes place at 03:01 BST on 12 August.
Wallace finished fourth and Lloyd came sixth in the same semi-final.
Phelps is the most decorated Olympian in history with 21 gold medals, two silver medals and two bronze medals.
He has won the 200m individual medley in the past three Olympic Games and has already collected a gold medal in Rio in the 200m butterfly, as well as helping the United States win two relay golds.
