May is expected to meet the first minister just a day before the Scottish Parliament is due to vote on whether or not to seek another independence vote.
Sturgeon claims that the referendum, planned to take place as soon as autumn next year or spring 2019, would allow the Scottish people to have a say on their destiny – namely whether they accept a ‘hard Brexit’ or would rather become an independent country.
The PM – who is set to trigger Article 50 of the Lisbon Treaty on Wednesday, kick-starting the formal process of exiting the EU – has previously made clear however that she will block Sturgeon’s call for another vote, saying “now is not the time.”
“Just at this point, all our energies should be focused on our negotiations with the European Union about our future relationship,” May said during an interview with ITV earlier in March.
“To be talking about an independence referendum will make it more difficult for us to be able to get the right deal for Scotland, and the right deal for the UK.”
Ahead of the meeting on Monday, May is expected to stress to staff at the Department for International Development in East Kilbride that the UK now more than ever needs “strength and stability” in light of Britain exiting the EU.
She is also set to highlight how the union’s “force” serves as an inspiration worldwide.
“UK aid is a badge of hope for so many around the world,” she will say, according to Reuters.
“It appears on the side of buildings, school books, medical supplies and food parcels in some of the toughest environments and most hard-to-reach countries on the planet.
“And it says this: that when this great union of nations – England, Scotland, Wales and Northern Ireland – sets its mind on something and works together with determination, we are an unstoppable force.”
Although Downing Street has said discussions will not center on a second independence referendum but rather on the two-year negotiations that will lead to the UK divorcing the EU, Scottish government sources have said the prime minister cannot concern herself with Brexit alone.
The meeting comes as the Labour Party prepares to set out its own requests for Brexit.
Shadow Brexit secretary Keir Starmer will on Monday share the party’s ‘six tests’ for the PM and the EU, which include guaranteeing the UK maintains the “exact same benefits” it currently enjoys inside the single market and customs union, something originally pledged by Brexit secretary David Davis.
On ITV’s ‘Peston on Sunday’ show, Labour leader Jeremy Corbyn said the party would block a Brexit deal if it took a toll on the country’s economy, despite overwhelmingly voting to trigger Article 50.
“We are very clear that there has to be unfettered access to the European market otherwise the threat to jobs in this country is absolutely huge,” Corbyn said.
A spokesman for Scotland’s Brexit minister Michael Russell said the Scottish government hopes to get some clarification on what the country’s role will be in Brexit negotiations.
Russell also said there had been no assessment of the financial impact Brexit would have on Scotland.
“There are clearly a lot of areas where we hope the prime minister intends to provide answers,” Russell told the BBC.
He also reiterated Sturgeon’s claim that a referendum is necessary for Scotland to decide on its own future.
“We believe it should be for the people of Scotland to decide their own future, which is why we will return to parliament on Tuesday to seek a mandate to begin discussions on a referendum that will put Scotland’s future in the people’s hands.”
