Robinson told BBC Radio’s Good Morning Scotland that the tax rise could cost the Scottish Government up to £500m.

“As the Scottish public sector is larger, we need to see it fully covered,” he added.

“We will seek urgent clarity on this matter.”

Around 600,000 people are employed in Scotland’s public sector, representing 22% of the total workforce, compared to approximately 17% in the UK as a whole.

This has fueled concerns at Holyrood that Scotland could be short-changed if compensation for the National Insurance increase is not proportional to its public sector.

Despite the additional funding, Robison said “austerity will continue for those affected by the two-child limit, and also by the loss of winter fuel payments.”

But the Finance Secretary stressed there would be no “bonanza” in easing Westminster’s policies, as she refused to commit to spending extra money to ease the two-child benefit cap or reinstate the universal winter fuel payment for children. pensioners.

He added: “Let’s be clear: the money we have received is largely for the NHS and frontline public services. This does not give us much leeway to spend on other things.”
