Definition of Disability in the UK

See this dispatch:

The Government was defeated in the Lords today when peers backed a Tory move extending anti-disability discrimination measures to people who had suffered depression and relapsed.

Voting on the Tory amendment during report stage of the Disability Discrimination Bill, was 138 votes to 131, a majority of seven.

The amendment covers people who have suffered serious depression that has interfered with their ability to function normally, have then recovered, but have suffered a relapse within five years.
