The First Minister of Wales should tell Scottish voters that he'd be prepared to see £4bn cut from Scotland's budget to boost the funding Wales receives, according to the SNP. Carwyn Jones will make the case for remaining part of the United Kingdom in a speech in Edinburgh this evening.
The SNP has highlighted the First Minister's repeated calls for fairer funding for Wales by reforming the Barnett formula which works out how much of a share of UK spending devolved nations should received.
But the SNP's Linda Fabiani says that if Scotland remains part of the UK after next year's Independence referendum and the formula is changed it will mean a cut of £4bn. She says Carwyn Jones should make that clear.
