In the debate last night Nick Clegg just used the word "nutters" when talking about the Conservative Party's European partners. It is a use of language he may come to regret. All three party leaders have agreed with the charity Rethink not to use words or language that will increase stigma against people with mental health problems. See HERE. By using the word "nutter" Clegg has already breached this pledge.
It may be a small thing to some people - and a case of political correctness gone mad for others - and of course people say many things in the heat of the moment, but a word of regret from Mr Clegg may be in order here.
