One million potholes a year will be fixed if Labour is elected on 4 July, shadow transport secretary Louise Haigh has said.

Under the proposals, councils will be funded to improve the condition of local roads and planning barriers will be removed to ensure infrastructure upgrades can be delivered.

The plan will be funded by £320m that will be saved by the deferral of the planned A27 bypass in the south of England.

Haigh said the Conservatives had failed motorists, adding: ‘The Conservatives have left Britain's roads plagued with potholes.

‘Labour is the only party truly on the side of drivers.

'Our plan will fix up to a million more potholes every year.'

The Asphalt Industry Alliance has estimated that £16.3bn would be needed to tackle the backlog of carriageway repairs and bring the road network up to a standard where it can be efficiently maintained.
