Prime Minister candidate Liz Truss came under scrutiny in 2009 over an alleged affair with a Conservative MP.
The Foreign Secretary, who is battling Rishi Sunak for the Tory leadership, has been married to accountant Hugh O'Leary since 2000. That same year, the then-25-year-old Mrs Truss reportedly first met Mark Field, who was a 36-year-old Conservative backbencher at the time.
Mrs Truss, a qualified accountant like her husband, was assigned Mr Field as a political mentor, according to The Mirror. Mr Field, who represented the Cities of London and Westminster, had studied law at Oxford, where he was a contemporary of Prime Minister Boris Johnson.
