Changing weather could help ease UK air pollution
High levels of air pollution are continuing to affect parts of the UK, according to experts.
Air quality data from Defra shows London and the South East experiencing pollution on Thursday at the maximum level of 10.
Levels in eastern England have reached nine - meaning high - with north-west England, the Midlands and south Wales also affected.
The Met Office expects changing weather to begin to move pollution in the next 24 hours.
