Story summary

As of November 10, 2026, London issued a high air pollution alert due to dense fog and light winds over the weekend that trapped emissions in urban areas. Government monitoring recorded Greater London as having "very high" levels on its 10-point index, while other regions like the South East and East Midlands were at "high" levels. The Met Office's chief meteorologist Jason Kelly explained that persistent high pressure brought light winds and clear skies allowing fog to form, slowing down pollution dispersion.

Experts like Larissa Lockwood from Global Action Plan noted this surge in pollution was expected during autumn when households light wood-burning stoves and have bonfires or fireworks. Mayor Sadiq Khan urged vulnerable residents to take precautions, including minimizing exposure to polluted air, switching off vehicle engines when stationary, and avoiding burning garden waste.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
