Kirsty Young's castaway is the campaigner Baroness Jane Campbell.
She was born with a degenerative condition and her parents were told she would not survive infancy. Now in her mid-fifties and a cross-bench peer, she's spent her adult life campaigning for equality for disabled people and was one of the leading voices behind the Disability Discrimination Act of 1995.
She recalls: "I found myself sitting in the middle of Westminster Bridge bringing the traffic to a standstill. The police didn't know what to do with us - whether to pat us on the head or, you know, put handcuffs on us. They were quite confused."
