Alex Salmond, who died earlier this month aged 69, was prime minister at the time, while John Swinney was finance secretary.

At Holyrood, the SNP is currently in power but governs as a minority administration.

This means they must rely on the support of other parties to pass legislation.

The Greens were in a power-sharing deal with the SNP until April, when then-prime minister Humza Yousaf kicked the junior party out of government.

The Scottish Government has since halted some Greens-backed policies, including funding for nature restoration and a pilot scrapping peak rail fares.

During his keynote speech, Harvie called on the SNP to reverse its “broken promises”.

He accused the Scottish Government of making an “abrupt U-turn” on climate policy since the Greens left government.

Harvie called for the reinstatement of the plan to provide free school meals for all primary school children and the reversal of cuts to the nature restoration fund, among other pledges.
