Olympics swimming: Shock exit for Ellen Gandy in butterfly

World championship silver medallist Ellen Gandy is a surprise casualty in the 200m butterfly heats, but British team-mate Jemma Lowe does progress.

Gandy was considered a serious medal contender, but after a strong opening 150m, faded on the last length.

Lowe's time of two minutes 7.64 seconds was the third quickest in the heats and she will now return for the semi-finals.
