Mrs Clinton, the Democratic frontrunner for the 2016 presidential election, has come under fire over revelations she had a secret email account as Secretary of State.
She has repeatedly insisted that she did not send or receive any classified information on her private account.
However it has emerged that among a host of emails sent and received by Mrs Clinton from her private account include at least 30 relating to 'foreign government information'.
Experts said any information from foreign governments -- including the UK -- is 'presumed classified' and should never be sent to private email accounts to protect national security and the integrity of diplomatic relations.
