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".
Shadow chancellor John McDonnell has told ITV News' Deputy Political Editor Chris Ship raising the top rate of income tax to 60p will be a topic in Labour's economic debate.
"At the moment the Labour party policy is to take it back to the 50," he said. "(Putting it up to 60p) will be part of the debate we have."
Mr McDonnell also confirmed he would look to meet with Bank of England governor Mark Carney to discuss Labour's plans to review the bank's mandate as part of the party's reinvention of its economic policy.
He said the governor's recent criticism of potential Labour policy was "wrong" because he had failed to "listen" to the party's new top team.
