Jazz Carlin through to 400m freestyle final

Great Britain's Jazz Carlin has claimed a spot in the women's 400m freestyle event at the World Swimming Championships in Kazan.

The 24-year-old, who won the silver medal at this distance in last year's Commonwealth Games, tied for second in her heat, seeing her through as the sixth-fastest competitor.

American Katie Ledecky set the pace, posting a time of 4:01.73, just over three seconds off the time she swam last year to break the world record.

The medals will be decided when the final takes place later today.
