A mum whose daughter was born with a heart defect is doing a sponsored swim to thank the doctors and nurses that saved her life.

Witham woman Michelle Murphy is taking part in the British Gas Great East Swim in Ipswich this Saturday to raise money for Evelina Children's Hospital in London.

Her daughter Rosey was born in 2007 with a blocked heart valve.
