Clinton Trump Ouch

Hillary Clinton's team are claiming victory in her debate with Donald Trump and this is the moment they say she sealed the deal.

The debate raged for 90 minutes, all broadcast live on LBC and viewed by millions on TV in the USA, but this was the key attack on Trump from Clinton.

Targeting Trump's temperament and foreign policy, Clinton told the audience: "He has said repeatedly that he didn't care if other nations got nuclear weapons, Japan, South Korea, even Saudi Arabia.

"His cavalier attitude about nuclear weapons is so deeply troubling.

"That is the No.1 threat we face in the world and it becomes particularly threatening if terrorists ever get their hands on any nuclear material.

"A man who can be provoked by a Tweet should not have his fingers anywhere near the nuclear codes."

Most commentators called the debate for Clinton, but admitted that Trump had run her close in the first half of the exchanges. There were further exchanges about presidential temperament - including some fascinating facial expressions from both candidates - here:
