But if you’re travelling through parts of Wales that are not connected by the rail service, you are obliged to go by car. So, obviously, we need the M4 to connect that east-west part of south Wales. But the M4 was not intended as a bypass around Newport or a commuter route into Cardiff.

The new natural resources policy promises a modal shift away from roads for people and freight, aimed at reducing emissions and the impacts that transport has on the environment and people’s health. The M4 relief road would do the opposite. The Welsh Government even admits it would increase the traffic, but tries to argue that it would reduce congestion and, therefore, air pollution. However, it might temporarily reduce congestion around Newport, but it would simply move the problem west to Cardiff. Cardiff already has highly congested areas in my constituency, affecting at least five schools having illegal levels of air pollution. The M4 relief road would make that a whole lot worse. This is not an effective use of over £1 billion. Instead, we could and should be investing that money in the metro, which would deliver the modal shift that our growing capital city urgently requires.
