'It's the best feeling in the world' - Siobhan wins silver
Siobhan Marie O'Connor from Bath has won silver in the 200 metre medley.
The 20-year-old smashed the British record to take second place in 2mins 06.88secs - just three tenths of a second behind Hungary's Katinka Hosszu who had to set a new Olympic record of 2:06.58 to win her third gold of the Games.
It has been a battle for the swimmer, who made her Olympic debut at London 2012 at just 16. Soon after she was diagnosed with the debilitating colon condition ulcerative colitis - and so her triumph is all the more impressive.
Her grandparents David and Doreen Hotham stayed up to watch Siobhan's success at their home in Winsley in Wiltshire.
