Cheese maker warned against supplying Gloucester cheese rolling 23 May 2013 Last updated at 17:25 A cheesemaker has been told by police she may be liable for legal action if she supplies Gloucester's famous annual cheese rolling. The traditional event involves revellers chasing a 7lb (3kg) wheel of Double Gloucester down Cooper's Hill. Diana Smart, who makes the cheese for the event at her Churcham farm, said she had been warned by police about her responsibilities as organiser. She said: "It made me feel pretty angry... there's not a lot we can do," Mrs Smart, 86, who has made cheese for the event for 25 years, said police had warned her she could be regarded as responsible if anybody was injured. Cheese rolling at Cooper's Hill features competitors chasing a wheel of cheese down a steep hill, and dates back to at least the early 19th Century. Some 15,000 people turned up for the last official cheese rolling event in 2010 but Cooper's Hill, near Brockworth, is only suitable for about 5,000. Unofficial races organised by local enthusiasts have been held during the late spring bank holiday each year since. A Gloucestershire Police spokesman said: "Advice has been given to all those who have participated in any planning of an unofficial cheese rolling event this coming bank holiday. This included the individuals who provide the cheese. We feel it is important that those who, by law, could be constituted as organisers of the event that they are aware of the responsibilities that come with it so that they can make an informed decision about their participation.
