M4 congestion 'must be dealt with', says Edwina Hart
Transport Minister Edwina Hart has insisted that traffic problems around Newport must be dealt with, after two former Labour ministers criticised plans for an M4 relief road.
She told BBC Wales that no final decision had been taken to build a new road to the south of the city.
The decision will be made after the 2016 assembly election, she said.
Former environment ministers Alun Davies and John Griffiths have both spoken out against the scheme.
The preferred, so-called "black route" for a relief road between junctions 23 and 29 of the M4 goes through the Gwent Levels wetlands, which environmental groups say is an important wildlife habitat.
