Newport M4 relief route decision faces legal challenge

The route chosen for the £1bn M4 relief road south of Newport could be legally challenged by Friends of the Earth Cymru.

The so-called "black route" between junctions 23 and 29 goes through the Gwent Levels.

However the environmental group has claimed a cheaper and quicker alternative to build - the "blue route" - was not given enough consideration.

Transport Minister Edwina Hart had said she expected a challenge to the route.
