A member of the Royal Navy has died after a Merlin Mk4 helicopter crashed in the Channel off the coast of Dorset during a night-flying exercise.
Two other crew members were rescued after the crash, which took place during training with the HMS Queen Elizabeth aircraft carrier.
The victim has not been named but their family has been informed.
On Thursday afternoon Keir Starmer said he was “deeply saddened to hear of the tragic death of a member of the Royal Navy”. The prime minister added that his “thoughts are with the family and loved ones during this painful time” and he paid tribute to those involved in the rescue operation.
In a statement, the Royal Navy said: “It is with great sadness that we must report a member of the Royal Navy has died following a training incident last night. Our thoughts are with the family – who have been informed – and all those affected at this sad time. A full investigation will take place.
“The incident involved a Merlin Mk4 helicopter in the English Channel near Dorset that ditched while conducting night-flying exercises with HMS Queen Elizabeth. There were no other fatalities or serious injuries.”
John Healey, the defence secretary, confirmed that an investigation into the cause of the crash was taking place. The incident, he said, was “dreadful news”.
