At around 3pm yesterday (July 24) ten fire engines and around 70 firefighters tackled a grass fire in South Ordnance Road, Enfield.

A London Fire Brigade spokesperson said: "We’re urging people to take extra care and help us prevent fires on open land this summer.

“Make sure rubbish, especially glass, is safely thrown away and cigarettes are always properly disposed of.

"Grass will be tinder dry after periods of hot weather, so please don’t have barbecues in parks and public spaces."

Anticlockwise traffic on the M25 was briefly held between junctions 27 and 25 due to "a fire in an adjacent field".
