Row over Anglesey port redevelopment funding

The idea is that Anglesey could become a so-called energy island - building up expertise in green energy like windfarms, along with a possible replacement for the Wylfa nuclear power station.

To make that dream a reality, Holyhead port needs substantial improvements costing anywhere up to £60m.

But who will pay for it?

That issue first came up at the end of last year, but a visit on Monday by the UK energy minister pushed it back up the political agenda.
