The Australian Prime Minister is laughing off the leak of footage showing him mocking Donald Trump.

The impersonation was rolled out by Malcolm Turnbull at a Parliamentary ball on Wednesday night.

"Not the fake polls, they're the ones we're not winning in. We're winning in the real polls. They are so easy to win. I have this Russian guy. Believe me, it's true."

Turnbull assumed the footage wouldn't be made public, as is protocol.

But he has brushed the leak off, insisting politics is a stressful business and you've got to have a laugh.
