Nicola Sturgeon has lodged proposals to cancel recess at the Scottish Parliament amid the increasing threat of Scotland crashing out of the EU.
The fortnight Easter break is due to start at the end of the week as a no-deal departure looms large.
MSPs discussed on Tuesday the possibility of sitting during recess, with a two-day recall on April 11-12 at the centre of talks.
The First Minister’s spokesman said: “We think it is prudent for parliament to be ready to sit next week.
“We should certainly be prepared, willing and able to sit. That is our proposal from cabinet.”
MPs could not agree on Monday night to an alternative way forward to Theresa May’s Breixt deal, which has been rejected three times by the Commons.
That leaves the legal default as an April 12 departure on a no-deal basis, unless agreement for an Article 50 extension can be secured from Brussels.
The FM’s spokesman added: “The First Minister’s view is clearly MSPs should not be on holiday when the biggest, most momentous, potentially most damaging issue to hit Scotland and the UK since the Second World War is about to take place.”
Ross Greer, a Green MSP, immediately hit out at the proposal on Twitter, saying “recess isn’t a holiday” but a chance to catch up on constituency work.
He told Ms Sturgeon’s spokesman: “You know that. Spinning something else won’t help you win over MSPs to this proposal.”
But his party backed the plan within minutes.
A spokesman for the Scottish Greens said: “Clearly, given the potential consequences of a no deal Brexit, it is quite right that parliament sits next week, in order that it can appropriately hold government to account in the face of this unprecedented crisis.”
The Scottish Conservatives were less enamoured by the prospect.
Maurice Golden, the party’s chief whip, said: “If there’s a genuine reason for parliamentarians to scrutinise government decisions or legislation next week then of course the Scottish Conservatives will consider supporting it and attend parliament as appropriate.”
A Scottish Parliament spokeswoman said the matter was considered by MSPs at its bureau on Tuesday, which decides Holyrood’s order of business, and there will be further deliberations by the end of Thursday, the last day parliament is due to sit before Easter.
