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 defence secretary Maria Eagle has criticised Jeremy Corbyn for saying he would not launch a nuclear strike if he was prime minister.
The Labour leader, who said he could "obviously" imagine being in Number 10, stressed he has a mandate from party members for his opposition to renewing the Trident nuclear deterrent.
But shadow defence secretary Maria Eagle said the comments were unhelpful and said they "undermined to some degree" the review she is carrying out of the party's defence policy.
Ms Eagle told the BBC that Labour's current policy is in favour of retaining a nuclear deterrent, adding: "I don't think that a potential prime minister answering a question like that, in the way in which he did, is helpful."
