Mayor of London Sadiq Khan [@SadiqKhan]

• THE Mayor of London Sadiq Khan is allegedly so concerned about pollution. He should come to South End Green and observe the 168 bus stand.

Buses are parked here throughout the day with their engines running, despite prohibiting signs, and hospital patients and staff walking alongside them.

How healthy is this? I have been complaining for years about this but with no result to date. Excuse after excuse for lack of action!
