One of Britain's most respected naval veterans has said "nothing's gone wrong" with the brand-new £3 billion aircraft carrier which has sprunk a leak during trials.
HMS Queen Elizabeth, the Royal Navy's future flagship, has a problem with one of its propeller shafts and has been taking on up to 200 litres of sea water every hour.
But Admiral Chris Parry, who joined the navy in 1972 and rose to the highest ranks of the service, told Mike Graham and Rachel Johnson the trials are designed to probe for flaws like this.
"This is brand-new technology, she's the biggest ship we've ever built," Parry told us.
"When she comes into service, she'll be worth the £3 billion."
