APPEAL judges have overturned a refusal over the Welsh government's Internal Market Act court challenge.

Leaders in Cardiff say the controversial legislation "seeks to impose the UK Government's will on Wales, in a way that disproportionately favours the interests of England".

The Westminster legislation has been described as a "power grab" by the Scottish Government.

The Welsh government announced a plan to take UK ministers to court earlier this year.

However, this was refused, with a High Court justice calling the case "premature".

That's now been overturned by the Court of Appeal. A request for a judicial review will now be heard.

Today Mick Antoniw MS, Counsel General and Minister for the Constitution, said: "We expect a hearing will be listed in due course. I will continue to keep Members updated about progress."

The Internal Market Act came into force as the Brexit transition period ended at the turn of the year.

Boris Johnson's UK Government says the move avoids a divergence in standards on goods and services emerging between the UK nations. However, there are fears in Cardiff and Edinburgh that this will remove autonomy and see decisions made in London impact on devolved areas.

Welsh Secretary Simon Hart has called Mark Drakeford's Labour administration "childish" and accused it of trying to block UK attempts to create jobs and prosperity.

But the Court of Appeal said the case raises "important issues of principle" about the relationship between Westminster and the Senedd.

Antoniw said the court had noted "compelling reasons for this appeal to be heard".

The initial refusal came after High Court justices decided the case was "premature", with the specific circumstances needed to test the claim lacking.

Responding to the news, Tory MP Hart said: "They're trying to stop us creating and sustain jobs in Wales on a point of power.

"All we are doing with the UK Internal Market Act, with widespread support from stakeholders across Wales, is to make sure we can spend money, attract investors and create jobs.

"If they are successful in this appeal that's what they will stop. It is really mystifying."
