The head of MIT's Media Lab has resigned following allegations that the academic centre has financial ties to the late US financier Jeffrey Epstein.
MIT President Rafael Reif confirmed the resignation of Joichi Ito on Saturday following media reports.

A spokesperson for Mr Gates told the New Yorker that "any claim that Epstein directed any programmatic or personal grantmaking for Bill Gates is completely false".
