British swimmers Hannah Miley and Siobhan-Marie O'Connor have progressed through to the semi-finals in the 200m individual medley at the World Swimming Championships in Kazan.
O'Connor, who earned the gold medal in this event at the Commonwealth Games last year, won her heat to post the second-fastest time of the morning.
Miley went in the final of four heats, and did enough to go through with the seventh fastest time.
The semi-finals will take place at the Kazan Arena later today, with the medals being decided tomorrow.
