A head and his staff have found a novel way to encourage good results from their pupils.

Jeff Hughes of Penketh High School in Warrington promised to perform Psy's Gangnam Style if students did well in their GSCEs.

However pupils were unaware their teachers had filmed a shot-by-shot recreation of the famous video, which was screened at their leavers' assembly.
