Few businesses have been founded on the basis of success in a headstand competition. But St Neots and Cambridge accountants Whitmarsh Sterland was, and is now celebrating 50 years in business. Founder John Sterland, pictured above, recalled the day garage group owner Ian Mantle had promised him his business if he won.
