Hillary Clinton last night demanded the FBI disclose all the information it had on the latest batch of emails after the bureau’s director, James Comey, announced the reopening of its investigation into her use of a private server.

With the election only 11 days away, Mr Comey’s intervention is the latest twist in the email controversy, triggering yet another day of high drama in what has been a roller coaster election campaign.

Having previously decided that there were no grounds to prosecute the former First Lady, he stunned the Clinton campaign by saying that the new batch of emails were “pertinent to the investigation”.
