Girls rule pool as world records tumble

Hungary's 'Iron Lady' steals the show with stellar 200m IM performance

Girl power prevailed at the world swimming championships on Monday as three women's records fell and Hungary's 'Iron Lady', Katinka Hosszu, lived up to her nickname.

After Katie Ledecky bettered her own 1,500m freestyle world record in the morning's heats and Sweden's Sarah Sjostrom broke her 100m butterfly mark, Hosszu claimed the 200m individual medley record which has stood since 2009.
