A big Tory majority election victory would see Theresa May's government "walk all over Wales, Scotland and Northern Ireland", First Minister of Wales Carwyn Jones has told ITV News.
He rejected the prime minister's justification for calling a snap election, saying: "This is not about trying to strengthen her hand with Europe. This is to centralise power in London."
Mr Jones backed Jeremy Corbyn's Labour campaign pledge to end the era of austerity.
"Austerity is a political choice, it's not an economic necessity," he told Wales Correspondent Rupert Evelyn.
"We've had seven years of it now ... and it's getting worse and worse and worse. I think people want an alternative and we've got to deliver that alternative."
