Jeremy Corbyn has told ITV News he would "live with" Trident "somehow" if Labour voted to renew Britain's nuclear deterrent.
The new Labour leader said he would do his best to persuade his party that the £100 billion-weapons system should be scrapped.
ITV News Political Editor Tom Bradby questioned whether Mr Corbyn "would be seen as willing to sell out his principles for power, like so many others".
Jeremy Corbyn has urged David Cameron to intervene to stop the execution of a young demonstrator in Saudi Arabia.
"Intervene now personally with the Saudi Arabian regime to stop the beheading and crucifixion of Ali Mohammed al-Nimr, who is threatened with the death penalty for taking part in a demonstration at the age of 17," he said.
He added: "While you're about it, terminate that bid made by our Ministry of Justice to provide prison services for Saudi Arabia which would be required to carry out the sentence that would be put down on Ali Mohammed al-Nimr.
"We have to be very clear what we stand for in human rights, because a refusal to stand up is the kind of thing that really damages Britain's standing in the world."
