A shadow cabinet showdown over Labour's policy on the future of Britain's Trident nuclear deterrent has been postponed.
Jeremy Corbyn's top team had been expected to discuss the proposals in the party's defence review at their weekly meeting at Westminster.
However it is understood that the debate has now been referred to a future meeting.
While there was no immediate explanation for the move, it follows a warning by shadow home secretary Andy Burnham that the differences within the party on the issue may be impossible to reconcile.
