George Clooney has vowed that Donald Trump will not be elected president, promising that "fear is not going to be something that drives" the United States.

Clooney spoke to reporters on Thursday at the Cannes Film Festival where he stars in Jodie Foster's hostage thriller Money Monster. Clooney, a prominent fundraiser for Hillary Clinton, insisted that Mr Trump will not win.

Clooney and his wife, human rights lawyer Amal Clooney (who joined him on the Cannes red carpet for the premiere of Money Monster), last month hosted a pair of events in Los Angeles and San Francisco that raised millions for Mrs Clinton, the Democratic presidential candidate nominee.
