One of Hillary Clinton’s closest aides is at the centre of the new FBI investigation into the Democrat candidate's emails after it emerged the evidence was discovered during an investigation into her husband.

Anthony Weiner is being investigated over allegations that he sent sexually explicit text messages to a 15-year-old girl, in the knowledge that she was still at school. Prosecutors in North Carolina, where the teenager lives, and in New York, where 52-year-old Mr Weiner is based, have opened inquiries.

Preet Bharara, the New York prosecutor known as one of the toughest in America, issued a subpoena for Mr Weiner's mobile phone and other electronic records after the “sexting” came to light in September. It is believed this sparked the reopening of the closed investigation.

“In connection with an unrelated case, the FBI has learnt of the existence of emails that appear to be pertinent to the investigation,” wrote James Comey, FBI director, in a letter to Congress on Friday.

He did not specify what the “unrelated case” was, but it was widely believed to be that of Mr Weiner – the estranged husband of Huma Abedin, 40, Mrs Clinton’s closest aide.

Mrs Clinton thought that the issue of her email server – which has been a millstone round her neck since 2012 – was finally settled, with the FBI deciding in July not to charge her with any criminal offence.

Now commentators are noting how ironic it is that Mrs Clinton’s presidential campaign could be critically damaged by her most loyal aide – loyalty being the quality the Clintons prize above all others.
