The UK’s new aircraft carrier, HMS Queen Elizabeth, has returned from sea trials early after a leak was found.
The Royal Navy’s future flagship left Portsmouth Naval Base last month for five weeks of sea trials and training.
A Ministry of Defence (MoD) spokeswoman described the leak as “a minor issue with an internal system” on Britain’s biggest warship.
The £3.1bn ship returned to Portsmouth as a precautionary measure after the leak was found on Tuesday.
Water leaked into an internal compartment, where it was contained.
It was pumped out and the 900ft (280m) long warship returned to port.
The MoD said: “An investigation into the cause is under way.”
This latest problem follows a number of other issues including a shaft seal leak, which caused water to pour into the ship, and the accidental triggering of the sprinklers in the hangar.
In May the captain of the aircraft carrier was removed from the ship amid claims he misused an MoD car.
