First Minister Nicola Sturgeon speaks to new PM Rishi Sunak
First Minister Nicola Sturgeon has spoken to new Prime Minister Rishi Sunak on his first day in office.
Afterwards Ms Sturgeon said that the call with Mr Sunak had been "constructive".
And the prime minister confirmed he "emphasised" their duty to work closely together.
It came just hours after the former chancellor succeeded Liz Truss and became the UK's third prime minister since September. 
Ms Sturgeon tweeted: "I expressed hope that we will build a UK/Scot gov relationship based on mutual respect - inc for mandates - and my fear that further austerity will do real damage to people & public services. I look forward to further engagement soon."
Last month Ms Sturgeon revealed she had not had a phone call with Ms Truss more than a month after she became prime minister.
But Mr Sunak spoke to both the first minister and her Welsh counterpart Mark Drakeford on Tuesday evening.
He later posted: "I emphasised our duty to work closely together to respond to the shared challenges we face, so that collectively we can deliver for the people of the United Kingdom."
Earlier, the new prime minister confirmed that Alister Jack will continue in his role as Secretary of State for Scotland.
Mr Sunak announced his new cabinet shortly after being invited to form a new government by King Charles.
uded Jeremy Hunt remaining as Chancellor, James Cleverly as foreign secretary, Ben Wallace as defence secretary and Suella Braverman returning as home secretary.
Liz Truss went seven weeks and her entire career as prime minister without speaking to the Scottish and Welsh first ministers but Rishi Sunak has done it on day one. 
I imagine they'll see a courtesy phone call as a low bar to cross, but it's a start.
For all that Mr Sunak is making more of an effort to engage with Nicola Sturgeon, I don't know if their relationship will necessarily be much warmer.
In the summer he said her plan for an independence referendum was "barmy" and that he wanted to "take her on and beat her".
PM's relationship with Scotland and Holyrood will also have a big bearing. 
He has talked about leading the "most active UK-wide government in decades", ending the "devolve and forget" approach and holding the Scottish government to account. 
All of which will inevitably spark clashes with Scottish ministers.
During the Conservative leadership contest in the summer Ms Truss made headlines when she claimed it was best to ignore "attention seeker" Ms Sturgeon.
But Mr Sunak later said ignoring the SNP would be "dangerously complacent".
And he described Ms Sturgeon and her party as "an existential threat to our cherished union".
On Monday the first minister congratulated Mr Sunak but urged him to call an early general election.
She also warned he must not unleash a new wave of austerity on the UK.  
And commenting on Mr Sunak's opposition to her plans for another Scottish independence referendum, Ms Sturgeon said it was for the people of Scotland to decide.
She added: "Scottish democracy will not be the prisoner of Rishi Sunak or any British prime minister."
