The Government has committed to banning the sale of all new diesel and petrol cars by 2040 in a bid to encourage people to switch to electric and hybrid vehicles.

But motoring experts have raised a series of concerns over the Government's clean air strategy.

We have taken a look at the initial reaction to the proposals:

'A tall order'

Jim Holder, editorial director of What Car? magazine, said it would be "a tall order" to increase the market share of electrified vehicles from 4 per cent of new car sales today to 100 per cent in just 23 years.

"The car industry has proved time and again that it can hit demanding targets, but at the moment electrified cars are both more expensive and less usable than traditionally-engined ones," he said.

"These are hurdles that must be overcome to win over car buyers."

Mr Holder said concerns over the charging infrastructure, the response of drivers to electric cars and the loss of billions of pounds of fuel duty meant "the risk is that this announcement creates more problems than it solves".
