Between them Avon & Somerset police and the Met police have issued 97% of the 700,000 tickets issued since 2018 for speeding at between 20 and 30 mph
The Met alone has issued 595,000 tickets the equivalent of 1 for every 4 cars registered in London.
Over the same period, six forces — Lancashire, West Mercia, Cleveland, Humberside, Warwickshire and Lincolnshire — have not issued a single ticket for 20mph offences despite all of them having 20mph limits in operation.
