Nigel Farage faces legal threat after linking Jo Cox widower to 'extremists'

Nigel Farage has been threatened with legal action over an extremism row with the husband of murdered MP Jo Cox following the Berlin terrorist attack.

Campaign group Hope Not Hate said it had asked the former Ukip leader to apologise for suggesting its supporters "masquerade as being lovely and peaceful but actually pursue violent and very undemocratic means" or face legal action.
