Donald Trump’s new communications director has launched an extraordinary, foul-mouthed tirade against two senior colleagues, raising the prospect of all-out civil war at the White House.

Anthony Scaramucci told an interviewer that Chief of Staff Reince Priebus is “a fucking paranoid schizophrenic” who will be asked to resign, and that Scaramucci is not like Steve Bannon, the chief strategist, because “I’m not trying to suck my own cock”.

The profane language was shocking even by the standards of the Trump era and suggested that a major staff shake-up is imminent, or perhaps, Trump himself is about to sink into the Atlantic Ocean.
