Democratic Unionist Party leader Arlene Foster agreed to prop up Theresa May’s minority Government this morning in exchange for the eye-watering sum. Welsh First Minister Carwyn Jones, of the Labour Party, described the cash injection as "bung" which flew in the face of Government commitments to fair funding for the nations and regions. Plaid Cymru said Wales should receive about £1.7 billion to match the cash being handed over in addition to devolved funds handed out under the Barnett formula. The Welsh Government put the figure at £1.67 billion over the course of the Parliament.

Today's deal represents a straight bung to keep a weak Prime Minister and a faltering Government in office Carwyn Jones

Mr Jones said: "Today's deal represents a straight bung to keep a weak Prime Minister and a faltering Government in office. "This is a short-term fix which will have far-reaching and destabilising consequences." "Only last week, we were told that the priority was to 'build a more united country, strengthening the social, economic and cultural bonds between England, Northern Ireland, Scotland and Wales’. “This deal flies in the face of that commitment and further weakens the UK, and as currently drafted all but kills the idea of fair funding for the nations and regions. "It is outrageous that the Prime Minister believes she can secure her own political future by throwing money at Northern Ireland whilst completely ignoring the rest of the UK. “I have spoken to the Secretary of State for Wales this morning to clearly state my view at this unacceptable deal - as Wales' voice at the Cabinet table, he has a duty to fight against this deal and secure additional funding for our country."

GETTY Wales has reacted with fury to news of Theresa May's £1bn deal with the DUP

Plaid Cymru's leader in Westminster, Liz Saville Roberts, said: "Despite Wales voting overwhelmingly to reject the Conservatives, we seem destined to be governed by the Conservatives once again, propped up by an extreme right-wing party opposed to gay rights, who criminalise women who have an abortion and is supported by armed terror groups. "Our country did not vote for this Government and Plaid Cymru will oppose this Government at every step of the way. "Any commitments for Northern Ireland should be matched for Wales. If reports that the DUP has secured a £1 billion increase in public spending in Northern Ireland are realised, Wales' population share would be around £1.7 billion - a substantial boost to the Welsh economy that must be delivered."
