Speaking after the meeting, Swinney said Westminster was “not working for Scotland or Wales” and that the UK Labour government had been an “unmitigated disaster for both our nations”.
He added that electing “strong, centre-left SNP and Plaid governments, we will also be sending a clear message that the hateful, extreme politics of Nigel Farage will never be allowed to win in our nations”.
Ap Iorwerth, whose party scored a dramatic win in last week’s Senedd by-election in Caerphilly, said a Plaid government in Wales and an SNP government in Scotland would result in “a powerful bloc”.
He said: “By electing a Plaid Cymru government able to forge a strong relationship with an SNP Scottish government, we can make our nations’ voices heard in Westminster and demand that Wales gets parity of funding and powers with Scotland as the first step towards taking our future into our own hands.”
A Reform UK Wales spokesperson said the meeting had “raised the stakes for next year’s Senedd elections even further”.
“Plaid Cymru are copying the SNP’s homework, even though they have delivered the highest drug deaths in Europe, higher income tax than the rest of the UK and an obsession with breaking up the union to the detriment of our NHS.”
