Scottish finance secretary Kate Forbes is calling for ‘urgent clarification’ about how much money the health service in Scotland will get from Westminster to deal with coronavirus.

It comes as the UK budget announced today by chancellor Rishi Sunak ramped up spending across the economy in a bid to lessen the economic impact of covid-19. He promised the NHS would get “whatever it needs” to tackle the crisis.

The first case of the virus spreading in Scotland not linked to travel or contact with an infected person was confirmed today, as the total number of UK cases climbed to 436.

An additional £640m will go north of the border as a result of the spending pledges, according to the Treasury. New measures include a freeze on business rates in England and changes to welfare and sick pay rules.

But Scotland’s recently appointed finance secretary says more detail is needed rapidly: “While I’m pleased to see the UK government’s economic response to coronavirus following my calls for this at the UK Treasury yesterday, we need confirmation on what this will mean for Scotland.

“We require urgent clarification on what funding Scotland will receive from the announcements made by the UK Government, at a time when the prospects for the economy and public finances remain very uncertain as the short-term impacts of COVID-19 unfold.”

She added: “We expect full consequentials from this additional funding and need urgent clarification to provide clarity for Scottish businesses and NHS Scotland to ensure we can respond effectively.”

GPs and the wider primary care system are likely to see “significant capacity challenges” if the virus surges and bosses have been told to move non-essential staff to frontline roles.

Amid uncertainty about how much cash would be available, Kate Forbes pledged in the Scottish budget last month that health spending in Scotland would increase to its highest ever level.

Other commitments included a funding boost for social care and £200m to make high street pharmacies the first port of call for more people with health issues.
