Does the government owe Wales £4bn because of HS2?published at 10:56 British Summer Time 13 June
Plaid Cymru leader Rhun ap Iorwerth said: "Wales is owed £4bn."
That refers to the demand to give Wales money under the Barnett Formula to reflect the billions spent on the high speed rail project.
Under the formula, public spending in England triggers money for Wales, Scotland, and Northern Ireland.
But despite not having any track in Wales, HS2 is classed as an England and Wales project.
The UK government in Westminster says Welsh railways are heavily integrated with railways in England meaning they should be considered as one network. Most rail infrastructure in Wales is the responsibility of the UK government.
When the government scrapped the northern leg of HS2, between Birmingham and Manchester, it promised to spend the money on other transport projects.
But instead of awarding money to the devolved administration in Wales, the UK government promised to spend £1bn electrifying the line between Crewe and Holyhead.
