At the second presidential debate in St Louis, Donald Trump and Hillary Clinton faced off on the most talked about issues of the day: his comments on sexual assault, Muslims, Syrian refugees, Ms Clinton’s emails and Obamacare.

But among the pointed barbs, the insults, accusations and interruptions, few clear statements on polices came forth during the 90 minutes.

Below is a round-up of what the Republican nominee said on the most important talking points of the debate.

The 2005 video which shows him bragging that he can grab women’s genitals.

“I'm very embarrassed by it, I hate it, but it's locker room talk. It's one of those things. I will knock the hell out of ISIS,”

On Bill Clinton

“What he's done to women, there's never been anybody in the history of politics in this nation that's been so abusive to women.”

On prosecuting Hillary Clinton

“I hate to say it but if I win I'm going to instruct my attorney general to get a special prosecutor to look into your situation. There has never been so many lies, so much deception. You ought to be ashamed of yourself,” Mr Trump said, and in response, Mrs Clinton said: “It's just awfully good that someone with the temperament of Donald Trump is not in charge of the law in this country.” Mr Trump replied: “Because you'd be in jail.”

Whether or not Mr Trump supported the war on Iraq

Ms Clinton said she had insisted for the "10th or 12th time" that Mr Trump had supported the invasion of Iraq in 2004, and the myth of his opposition had been “debunked”.

"It’s not debunked," he said. "It’s not debunked."

Taxes

Much speculation is circulating about whether Mr Trump used a loss of almost $1 billion in 1995 to avoid paying federal income tax for over almost two decades.

When confronted over whether he took advantage of tax loopholes, he said: "I absolutely used it, and so did Warren Buffett, and so did George Soros and so did many people who Hillary is getting money from."

On claims that he's sexist

“I have great respect for women. Nobody has more respect for women than I do.”

On what he respects about Hillary Clinton

“I will say this about Hillary - she doesn't quit, she doesn't give up. I tell it like it is. She's a fighter.”

On his immigration policies

"It’s called extreme vetting. We’re going to areas like Syria, where they are coming in by the tens of thousands because of Barack Obama and Hillary Clinton wanting to allow a 550 per cent increase [of refugees] over Obama.

"People are coming into this country. We have no idea who they are, where they are from and what their feelings are about this country."
