Lucy Hurst-Brown asks why so many learning disabled people are so lonely.

Having worked with learning disabled people for 25 years, Lucy describes a system which has moved a very long distance from the impersonal, institutional care of the twentieth century, but which still has a long way to go before learning disabled people are properly integrated into their communities.

And in describing how she and her colleagues realised they may be causing the problem, and how they set about finding a solution, she also challenges all of us to play our part.
