Update
My uncle is having a operation today; he has been moved to a specialist hospital, Addenbrookes, in Cambridge. I'm hoping to be able to visit him later today or tomorrow. We're all hoping it will find out what is wrong with him and that it will be treatable. He, and my family, were very pleased to hear some good news that I was able to share with them yesterday; I will blog later about it and share the news once I have checked the legal position.
