By Sally Williams, ITV Weather Presenter A high pollution alert has been issued by the Mayor of London - the first time since August 2020. Stagnant air and light winds are trapping pollutants over the capital and Home Counties. We are also drawing in pollution from Europe which is adding to the toxic mix in the air. According to Defra we could see moderate to high levels of pollution  over the next few days with some locally very high pockets of pollution on Thursday.
