Olympic bronze medallist and former 400 metres freestyle world record holder, Jo Jackson, has announced her retirement from competitive swimming.
The 26 year old, from Richmond in North Yorkshire, won her bronze in Beijing in 2008, and took silver in the World Championships the following year.
But after suffering from illness and injury, she couldn't reproduce the same form at the London Olympics earlier this year.
