The head of Boris Johnson’s Downing Street social media team was under pressure last night to resign for praising a far-right activist who is an associate of Tommy Robinson.

Ms Westley, who worked for the campaign group Taxpayers’ Alliance, described Ms Waters as “a hero” and said that her work should be widely published.
