British Olympic swimmer Melanie Marshall, best known for winning six medals at the Commonwealth Games in Melbourne in 2006, visited the Children’s Trust at Tadworth to help judge a special mini Olympics.

Children on brain injury rehabilitation programmes had the opportunity to take part in sporting activities including curling, skittles and basketball.

Marshall chatted to the children and presented medals and certificates to everyone who took part.

She also brought along a selection of her own swimming medals for the children to try on – the gold ones being especially popular.

Her visit coincided with the opening of the Trust’s new hydrotherapy centre, funded by the St James’ Place Foundation.

The £1.2m pool was the Foundation’s single largest gift in its 17-year history and will enable children from across the Trust’s services to benefit from hydrotherapy in purpose designed, multi-sensory facilities.

The hydrotherapy centre is part of the Children's Trust’s new £7.2m residential rehabilitation centre, which will be officially opened next month by Top Gear presenter Richard Hammond.

Andrew Ross, chief executive of the Children's Trust, said: “Hydrotherapy is of huge value in building up the strength of disabled children, particularly those who cannot support their own weight out of water, and this centre is second to none.”
