New diesel and petrol cars and vans will be banned in the UK from 2040 in a bid to tackle air pollution, the government is set to announce.
Ministers will also unveil a £255m fund to help councils tackle emissions from diesel vehicles, as part of a £3bn package of spending on air quality.
The government will later publish its clean air strategy, favouring electric cars, before a High Court deadline.
Campaigners said the measures were promising, but more detail was needed.
They had wanted government-funded and mandated clean air zones, with charges for the most-polluting vehicles to enter areas with high pollution, included in the plans.
After a protracted legal battle, the government was ordered by the courts to produce new plans to tackle illegal levels of harmful pollutant nitrogen dioxide.
