A HAMPSHIRE Liberal Democrat MP has said his party wants to see petrol powered cars banned from all UK roads by the year 2040.

Eastleigh MP Chris Huhne, the Lib Dems Environment spokesman, said the move was needed if the country was to effectively tackle climate change over the coming decades.

Mr Huhne said that under his party's proposals, cars would be powered by hydrogen fuel cells, improved battery technology or other new technology not yet developed.

Speaking alongside party leader Sir Menzies Campbell at Liberal Democrat HQ in central London, Mr Huhne told reporters there had been "far more dramatic changes" in Britain's economic history.

He said such a change compared with the shift from the steam engine to the internal combustion engine or from the gas light to the electric light at the start of the 20th century.
