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's leadership style is "very open, very democratic", one of his key shadow cabinet ministers has said.
Lucy Powell - who previously admitted she had never spoken to Mr Corbyn before he named her as shadow education secretary - said the new leader had consulted her and colleagues about his high-profile party conference speech.
Powell said she was impressed by the way the new Labour leader was "listening to people and taking their advice".
"I know other colleagues have been included in that process as well and that's something I very much welcome," she told Good Morning Britain.
"I expect that his speech today will be one laden with values - his values, the Labour values and actually the values of the British people as well. I think that's the message he's going to try to get across."
