The Duke of Cambridge has backed a campaign by the Amateur Swimming Association (ASA) which aims to ensure that every child has the opportunity to learn to swim.

In a recorded message, The Duke pledges his support by saying: "Swimming has always been important to me. As patron of the English School Swimming Association, I've been fortunate enough to witness at first hand the transformative effect learning to swim can have on children's lives.

"Learning to swim is not just about transforming lives. Swimming is unique as it's the only sport that can save lives. This is why I am so keen for school swimming to be accessible for all children at all primary schools.

"The results of a recent ASA study suggests that more than a million school children are unable to swim more than 25m. This report is especially important because it outlines some tremendous schemes and initiatives to help schools who might be facing challenges when teaching children to swim.

"The ASA has a belief, a vision, which I share, that every child has the right to learn to swim."

The report by ASA - Learning the Lesson, the future of school swimming - surveyed 3,501 schools on how many of their children have attained Key Stage 2 swimming requirements.

It found that half of children aged seven to eleven cannot swim the length of a typical swimming pool (25 metres) unaided, despite swimming being a compulsory element of the national curriculum.

David Sparkes, CEO of the ASA said: "The ASA's vision is that that every child should have the right and opportunity to learn to swim to help achieve a fitter, healthier and perhaps above all a safer generation of young people.

"I am delighted that His Royal Highness The Duke of Cambridge supports this vision and has provided support to our campaign."
