The plan to introduce a Clean Air Zone (CAZ) in Greater Manchester has been branded a "tax on jobs" by government ministers.
Set to be launched in May, the scheme is the largest of its kind in the country and will cover all ten boroughs - an area of around 493 miles.
The CAZ, which will hit drivers of high-emission vehicles, will see a £60 charge for HGVs, buses and coaches, £10 for vans and £7.50 for taxis and private hire cars.
