SNP Westminster leader Stephen Flynn has called on Chancellor Jeremy Hunt to deliver a £15 billion cash injection for the NHS in England.
He made the call as Mr Hunt prepares to present his spring Budget to Parliament next week.
Mr Flynn claimed that the additional cash would generate an additional £1.2bn for the health service in Scotland, which remains in crisis after a £1.6bn cut in capital funding in the Scottish budget led to a complete freeze on new capital projects.
“The UK government has already slashed Scotland’s budget by billions of pounds,” he said.
SNP Health Secretary Neil Gray said last month that he would be “happy to consider” expanding private provision to tackle waiting lists in the wholly devolved service.
Mr Flynn added: “Sunak and Starmer’s plans to slash funding, reduce staffing with Brexit and introduce creeping privatisation poses a very real threat to the wellbeing of our NHS, our care system and families across Scotland.”
The Treasury was contacted for comment.
