Susan Sarandon has caused controversy by stating why she is not voting for Hillary Clinton, even though doing so would prevent a Donald Trump presidency.

The actor said she does not "vote with her vagina" and will instead be voting for the Green candidate in the US election, Jill Stein.

Sarandon, 70, said she will not be voting for Clinton or Trump because she feels it is important to get third-party candidates up to the 5 per cent mark.
