M4 relief road around Newport 'will not have tolls'
Drivers would not be charged a toll to drive on a proposed M4 relief road in south Wales, the Welsh government has said.
The BBC has been told the Treasury is backing plans to build a new stretch of motorway around Newport.
A Westminster source said agreement in principle had been reached but a deal on funding was not finalised.
However, the Welsh government said introducing a toll to pay for the road would be "unfair" and "unworkable".
