Liam Tancock has cruised into the 50m backstroke semi-finals at the World Swimming Championships in Russia.
The Briton, who is a two-time world champion at the distance, finished third in his heat to go through with the sixth-fastest time of the morning.
He was less than half a second behind France's Camille Lacourt, who topped the timesheets after completing the distance in 24.56s.
American Matt Grevers was second, just ahead of Australian duo Ben Treffers and Mitch Larkin.
