Michael Moore has suggested Donald Trump is likely to be impeached because the Republican will break the law during his first term as President.

The Oscar-winning documentary-maker and left-wing political commentator, who in July correctly predicted the billionaire property magnate would win the presidential election, insisted Mr Trump’s first term would be cut short.

Moore said the wave of protests which have erupted across America in the wake of his victory were not likely to die down anytime soon.

“Here’s what’s going to happen, this is why we’re not going to have to suffer through four years of Donald J Trump, because he has no ideology except the ideology of Donald J Trump,” he said on MSNBC’s Morning Joe on Friday.

“And when you have a narcissist like that, who’s so narcissistic where it’s all about him, he will, maybe unintentionally, break laws. He will break laws because he’s only thinking about what’s best for him.”

Moore also said he believed protests would snowball after Mr Trump started choosing who was in his cabinet and making his Supreme Court appointments.

“We are going to resist. We are going to oppose,” he said. “Those demonstrations you're seeing on the streets. When it's in places like Milwaukee - that's not Berkeley and Ann Arbor. This is going to continue tonight and the next night. All he has to do is start nominating Rudy Giuliani as attorney general and things like that. Or [make] his Supreme Court [picks].”

“This is going to be a massive resistance. There's already - women are calling for a million woman march on the Inauguration Day. There's going to be the largest demonstration ever on Inauguration Day. We're also going to organise.”

Moore has been wearing a safety pin fastened to his clothing - a gesture some people are taking to show solidarity with minority groups in the wake of Mr Trump's victory.
