James was invited to entertain at 10 Downing Street yesterday to help the charity U Support which provides opportunities for children suffering with a disability, hardship or illness.
Founded by Adam and Tracey Gregory, U Support provides life changing experiences by helping disabled and disadvantaged children to attend sporting and cultural events with their carers.
The reception, to launch the charity's 'Opening Doors Campaign' was generously hosted by Samantha Cameron.
This is the third time that James has been invited to entertain in London's most famous street. He said, "It's a privilege to be here to support a small charity that does such amazing work. As U Support launches 'Opening Doors', the door of Number 10 seems like a very good place to start."
Prime Minister David Cameron said, "To have helped around 10,000 young people in just eight years is a marvellous achievement. I wish you and all at U Support every success for the future."
