John Swinney indicates his SNP Government will reach out to unionists to pass laws and budgets

In an apparent dig at his predecessor Humza Yousaf, Mr Swinney has admitted the SNP must “change how it talks to people” on the other side of the political divide to make progress as a minority government.

Mr Swinney is set to become the next SNP leader, despite an apparent last-minute bid for attention by an outspoken party activist who claims to have enough support to challenge Mr Swinney.

The former deputy first minister suggested he would move the SNP back to the centre-ground of politics after the Bute House Agreement with the Greens was ripped up.

But a Greens source had told Scotland on Sunday that “if the SNP moves too far to the right, they would need to look elsewhere to get their policies and budgets passed”, adding “we are not here to simply endorse an SNP minority government”.

Now Mr Swinney has signalled he will reach out to unionist parties such as Labour, the Liberal Democrats and the Conservatives in order to pass legislation and budgets as he draws up his plans to push ahead with a minority SNP government at Holyrood.

Mr Swinney said he would build a consensus with other parties by “engaging in respectful and courteous dialogue within the Parliament”, insisting “I believe in mainstream politics”.

He told the BBC’s Sunday Show: “I believe the SNP should pursue a moderate left-of-centre policy programme – that is where I come from politically. I want to make sure that is successful. We will bring these proposals forward to Parliament and work with others to advance those proposals.”

Asked if a minority government under his leadership could be propped up by anyone other than the Scottish Greens, Mr Swinney said: “I think we probably can do.”

He pointed to recent legislation on keeping the ‘Promise’ to care-experienced young people where SNP minister Natalie Don was able to “reach agreements with Labour and Liberal Democrat members about amendments to that Bill”.

But pressed over whether his unionist opponents would help pass a budget, given the hostile stand-off with the SNP over the constitution and other key issues, Mr Swinney said: “I don’t think we should rule that out.”

He added: “In the past I have had Liberal Democrat, Labour, Conservative, Green support for budgets.” The Perthshire North MSP said that if opposition parties would block his budgets on principle against an SNP government, “that’s their problem”.

“That won’t pay teachers, it won’t pay nurses,” he said. “It won’t make sure we can get operations done in our hospitals. If you don’t pass a budget, you can’t fund your public services. There becomes a responsibility on all of us.

“If we go back to 2009 when one of my budgets didn’t go through Parliament on the first time of asking, within a couple of weeks, the budget was passed – virtually in its entirety from what I had originally proposed. The opposition parties were challenged about how hospitals were going to be funded or schools were going to be funded or councils were going to be funded and they didn’t have any answers.”

Mr Swinney said: “A budget process puts a responsibility and an obligation on everybody, not just the Government. I accept the Government’s got to act differently to try to get people on board. The Government’s got to change how it talks to people.”

However, unionist party leaders have not indicated they would work more openly with an SNP Government headed by Mr Swinney.

Scottish Labour leader Anas Sarwar told the BBC “there is still a deeply chaotic and divided political party that I think has broken its trust with the Scottish people”.

“All of this is about managing his [Swinney’s] political party rather than running the country,” Mr Sarwar said. "I didn’t hear anything from John Swinney around any new direction around fixing our NHS, around getting our education system back on track.”

Labour national campaign co-ordinator Pat McFadden said his party was “not planning alliances” with the SNP “or anyone”.

Mr McFadden said a change in SNP leader “doesn’t make much difference”, in the wake of Mr Yousaf announcing his resignation as First Minister a week ago.

Asked if he “could imagine” Labour and the SNP working together if his party does not win a majority at a general election, Mr McFadden told Sky News’s Sunday Morning With Trevor Phillips “no”.

He said: “Our aim is to win a majority, to govern, to meet the mood for change, and we’re not planning any alliances or pacts with anyone.”

Scottish Conservative chairman Craig Hoy insisted “John Swinney is the ultimate continuity leader”.

He said: “He was joined at the hip to the disgraced Nicola Sturgeon and central to the cynical cover-ups and policy failures that characterised her government – especially as education secretary when Scotland fell sharply in the international rankings.”

Nominations for the SNP leadership close at noon on Monday. But one fly in the ointment of a coronation for Mr Swinney could be a suggestion that party activist Graeme McCormick used the independence march in Glasgow on Saturday to drum up support for his candidacy.

It is understood Mr McCormick believes he is very likely to receive the 100 nominations from at least 20 SNP branches before the Monday deadline, but no proof has yet been provided.

Should Mr McCormick receive the required nominations, a three-week leadership contest will be triggered, with ballots opening on Monday, May 13 and closing on May 27.

Mr McCormick has previously been critical of the SNP-led Scottish Government, using last year’s party conference to criticise its independence strategy.

Amid the speculation that a leadership contest would delay him becoming first minister, Mr Swinney said he would like to get on with that job “as quickly as possible”.

The former deputy first minister said he would respect the “democratic process” if there was a contest. But he added: “I think the SNP has got a chance to start rebuilding from the difficult period that we have had, under my leadership, and bluntly, I’d just like to get on with that as quickly as I possible can do, because every day that we spend in an internal contest, which I think we all probably know the outcome of, we delay the possibility for the SNP to start its rebuilding.”
