The Scottish government has struck deals with the Greens and Lib Dems to ensure that its Budget plans will be approved.

Finance Secretary Shona Robison said she would table a series of amendments to the Budget Bill after the two parties agreed to support the tax and spending plans.

The Greens had lobbied for measures including an expansion of free school meals to S1-S3 pupils who receive the Scottish child payment in eight council areas, while the Lib Dems argued for an additional £2.6m to be spent on drugs and neonatal services.

Scottish Labour had already said it would abstain in the vote in parliament, but the agreements mean that ministers can now guarantee MSPs will approve the Budget.

The minority SNP administration requires the support of three MSPs from other parties to ensure that its budget passes when parliament votes on the plans.

The Scottish Greens have seven MSPs, and the Lib Dems have four.

Finance Secretary Shona Robison said the new Budget proposals demonstrated the value of a progressive approach and dialogue.

She said: “Through seeking compromise I believe we are delivering a Budget that will strengthen services and support our communities.

“With the agreements with these two parties now in place this will secure a majority in parliament in support of the Budget Bill.”

Scottish Greens finance spokesperson Ross Greer said his party put climate action and tackling child poverty at the heart of the Budget negotiations, alongside funding for schools and cheaper bus and ferry fares.

“We have delivered progress on all of these fronts, so our MSPs will be voting for the budget,” he said.

Scottish Liberal Democrat leader Alex Cole-Hamilton said his party would always act responsibility and try to find common ground.

He added: “There is a long list of policies and projects that we’ve won for our constituents, and for Scotland as a whole, and so we will be voting for the Budget.”

The changes agreed in the Budget after the talks include:

• £2.6m worth of additional investment in drugs and neonatal services, including £1m for specialist support for babies born addicted to drugs
• A £2 bus fare cap pilot in one regional transport area
• Support for hospices to rise from £4m to £5m
• Increasing nature restoration by £3m
• £3.5m of targeted support for the college sector, including £700,000 for those attending Corseford College in Renfrewshire
• Extending free school meal eligibility in S1-S3 in eight local authority areas for pupils in receipt of Scottish Child Payment
• Flexibility for Orkney Island Council in terms of capital and resource funding

The budget already looked set to pass after Scottish Labour Anas Sarwar said the party’s 22 MSP’s would abstain from voting.

Sarwar had said his party would only vote in favour of the budget if ministers accelerated plans to effectively scrap the two-child cap on access to benefits.

The Scottish government is planning to do this in 2026, arguing that it will need time and the cooperation of the UK Department of Work and Pensions (DWP) to administer the change.

The Scottish Conservatives are expected to vote against the Budget because the plans do not include substantial tax cuts.

Instead, the government has said it will continue an income tax freeze until 2026.

Scottish Conservative finance secretary Craig Hoy accused the Lib Dems and Greens of “falling over themselves” to back “a bad Budget”.

“We’re standing up to the SNP as the only political party in Scotland representing common sense,” he said.
