Career
A captain in the 4th Battalion Grenadier Guards, Grey was killed at Le Repas in Normandy, France, on the first day of Operation Bluecoat. He was buried on the battlefield by his men, on the site of which his family later erected a memorial. The site is now recognised as a war grave, designated the Livry Isolated Grave.
William Beveridge retained Berwick for the Liberals in the subsequent by-election.
