Festival-goers to this year's Mela at Gunnersbury Park will be able to find out about diabetes.

The Diabetes UK's 'Measure Up' roadshow will visit on Sunday, August 8, to help people find out about diabetes and whether they are at risk.

People will have their waists measured and the campaign will target people who are over 40, of black or south Asian origin and those with a family history of the condition, because they are at greater risk.

Roz Rosenblatt, regional manager for Diabetes UK London, said: "Diabetes is one of the biggest health challenges facing us today."
