GB butterfly buddies impress at World Championships

British pair Ellen Gandy and Jemma Lowe, who are good friends and room together at major events, defeat former champions and the world record holder to qualify for the final of the 200m butterfly in Shanghai.

21-year-old Lowe will start as a surprise fastest qualifier for Thursday's final and the British team will hope she and Gandy can add to the silver medal won by Rebecca Adlington in China.
