While London is on a high pollution alert, please continue to protect yourself and others. Help solve the problem by avoiding driving, and instead use public transport, walk or cycle if you can. We all have the power to tackle climate change.

You’re such a pillock concentrate on a non problem while your citizens are getting stabbed, raped and robbed on the streets. Resign you useless waste of space and good oxygen

shut up.

Who do I believe? The impartial weather app telling me pollution where I am is low, or the person who is using pollution as an excuse for taxing people more 🤔

Sally Williams - you should be ashamed! I get it, you love your kids and love the cushty money but looking at ‘misty’ long distance pictures and judging it to be ‘bad’ pollution breaks every rule of science! What is the 2.5ppm pollution compared to New Delhi? @BigThickSlices

Yes walk or use the buses just like those young people who were murdered and ran over waiting at a bus stop in Nottingham You are a complete disgrace and you will be famous as the worst mayor this country has ever elected

Open up all the LTNs and clear the congestion they have created in London.

Protect yourself from the clean air! From the mayor's own monitoring stations that he's taking info from to tell you the air is toxic. Green almost across the board. Go out, enjoy the summer. Have fun.

Did you lead by example today? Or did you carry on being driven in your 5L diesel Range Rover Sentinel? Along with your mayoral cavalcade?

What like the tube!? Can’t anyway as we don’t have a train station for 4 miles in Biggin Hill & 45 minutes walk from the nearest bus stop to work. I do hope you aren’t driving in a convoy of vehicles to walk your dog when there is a park over the road with better air quality !
