I am indebted to Mr Don Perry (Industrial Editor, Sunday Express, 1964 -1982) for his letter to The Times today in which he informs me:
"Perhaps the Governments's own Employment Relations Act 1999, Section 3, which prohibits lists 'compiled with a view to being used... for the purpose of discrimination in relation to recruitment or... the treatment of workers', is relevant."
So there you go. Such lists are illegal.
