South Wales Metro impact on Valleys 'could take decades'

Valleys communities could be waiting decades for a boost from a new integrated transport system for south Wales, a leading economist has warned.

Prof Calvin Jones told BBC Wales' Sunday Politics Wales show that the South Wales Metro plan had raised hopes that the Valleys would immediately benefit.

The Welsh Government said the Metro would be "transformational" as they hope first services will be running on the network by 2023.

But Prof Jones said the first places to benefit "may indeed be in Cardiff".
