WikiLeaks: Clinton worried about Argentine leader

US Secretary of State Hillary Clinton questioned the mental health of Argentina's President Cristina Fernandez, asking US diplomats to investigate whether she was under medication, leaked cables showed on Tuesday.

Britain's Guardian newspaper - one of several publications to have had early access to US diplomatic cables made public by the whistle-blowing website WikiLeaks - quoted secret memos sent by Clinton to the US Embassy in Buenos Aires last December. Clinton asked diplomats a series of questions about the "interpersonal dynamics" between Fernandez and her late husband, Nestor Kirchner, and enquired how the 57-year-old leader was managing "her nerves and anxiety".
