A businessman has uncovered a 'treasure trove' of history in a Second World War air raid shelter tucked away underneath his office.

Entrepreneur Steve Shaw, from Stoke-on-Trent, made the discovery in the bowels of the Trinity Buildings in Hanley, Staffordshire.

The property has served as the base for his firm Euroseal Windows for more than a decade.

Mr Shaw says the shelter appears to have been used briefly as a photographic darkroom in the 1950s, but he believes that it has remained untouched ever since.

Items found in the cellar include original air raid signage, emergency supplies and tins of rations.
