A major UK city has been put under a “severe” fire warning as Britain’s heatwave continues.

London’s fire chief issued the warning for the capital, which could soar to 33C today according to the Met Office.

Thomas Goodall said a combination of high temperatures and low rainfall means people should be extra careful, and that firefighters have already been called out to 14 wildfires in the capital so far this year.

He warned: “We know that people will be looking forward to getting outside to enjoy the wonderful weather. But the high temperatures and low rainfall in recent months means the current risk of wildfires is severe.”

He advised: “During this latest heatwave, it is important everyone acts responsibly to prevent fires from occurring. As the weather has been so dry, it only takes a few sparks to lead to a fire spreading rapidly.

“In London, this is can be dangerous because so many of our green spaces lie close to homes and other properties.”

The fire chief added that there have been “countless callouts” to smaller fires involving grass, trees and gardens.
