She secured favours from the diplomats she had affairs with.
They helped her clients get South Korean visas, they also leaked classified information - allegedly even the president's mobile phone number.

Three diplomats have been sent home to face investigators. But it is not clear what has happened to the woman dubbed by one South Korean newspaper "the sexy siren - a femme fatale".
