He paid £180,000 hammer (£216,000 with commission) for the Stronach George Cross group at the Dix Noonan Webb sale on May 10. It was estimated at £120,000-140,000.
Lord Ashcroft has long been known for collecting outstanding examples of the Victoria Cross but in recent years has also built a reputation for buying GCs at auction, helping to raise the stature of this award to its proper level (it is the equivalent to the VC for civilians, and actions by members of the armed forces not in the face of the enemy).
Bomb disposal is a common GC theme but the Chief Officer George Stronach honour was one of just three awarded to merchant seaman during the Second World War.
He rescued comrades from the blazing SS Ocean Voyager, which was one of the vessels supplying the British Eighth Army as it fought its way westwards across North Africa. It had been moored in Tripoli with thousands of tons of aviation fuel and ammunition aboard when it came under low level attack from the Luftwaffe.
Previous George Cross purchases
In July 2015 Lord Ashcroft paid a record £260,000 hammer price for the GC awarded to Special Operations Executive secret agent Violette Szabo, again at DNW.
And in February last year he paid £120,000 for the GC group awarded to Wing Commander Leonard Harrison RAF, who worked in bomb disposal and is believed to have defused more unexploded devices during the conflict than any other man.
