The whole of southern England - including Devon and Cornwall - is likely to be hit by a huge cloud of air pollution this weekend.

The Government has warned that it will expose the most vulnerable to more health risks.

Low winds have pushed agricultural ammonia, particulates from fires and industry pollution over continental Europe towards the British Isles, reports the Mirror.

The cloud of pollution will cover southern England and parts of Wales, and is expected to hang over the Isles until Sunday.

The Department for Environment, Food and Rural Affairs warns that people with asthma and other breathing problems should avoid physical activity during periods of "very high pollution", as the UK is experiencing.

When coupled with the risk of catching the coronavirus, which has proved fatal for some people with respiratory problems, staying inside this weekend is advised for the vunerable.

Sunny spells are forecast to dominate over the weekend, with the temperature to hit the early-twenties celsius in the region.

Social distancing restrictions remain in the place across the country, meaning people without private outdoor space may find this weekend a frustrating one.

Councils throughout the UK have warned vulnerable people not to venture outdoors and for people not to light fires in their gardens.

Cornwall Fire and Rescue Service said: "Due to the ongoing challenges of COVID-19 we are reminding the public to cease all controlled burning until further notice.

"Call 999 as usual if you see smoke/fire & our Control Room will assess if an attendance is required."
