PLAID leader Leanne Wood called yesterday for a new law that would force Westminster to distribute Britain’s wealth equally as part of a “democratic economy.”

Ms Wood said a “legal duty” should be placed on government ministers to stop them lavishing vast sums of taxpayers’ cash on the “London city state black hole.”

The big idea of her 45-minute conference speech would mean Wales, Scotland and England’s poorest regions would receive the same investment level per-head as London.
