John Swinney is set to face MSPs at Holyrood the day after his party launched their election manifesto with a focus on independence and the NHS.
The SNP vowed to immediately seek independence negotiations with the UK Government if it returns a majority of MPs to Westminster.
The party also said it wants the next prime minister to give Scotland another £1.5bn a year for the nation’s NHS, rejoin the EU and end the two-child benefits cap.
Scottish Greens launched their manifesto on Thursday which proposes a wealth tax and an end to oil and gas companies advertising.
The party would also levy a private jet tax of £1,000 per head against those using their own planes to travel to or within the UK.
