THE Scottish Government’s future hangs in the balance as Scottish Green members weigh up whether they want to continue their deal with the SNP.

Discontent over a series of policies – including the council tax freeze, children no longer being prescribed puberty blockers – came to a head last week when it was announced the Scottish Government was abandoning a key climate change target.

Green members put pressure on the party leaders who have now referred the Bute House Agreement – the deal which put them in a quasi-coalition with the SNP – to the grassroots for a vote.

There are a few ways things could pan out. In no particular order, the options are:  

Greens pull out, SNP return to minority government

If Green members directed their leaders Lorna Slater and Patrick Harvie to pull out of the Bute House Agreement, the SNP could well be back to the days of running a minority administration.

Humza Yousaf would likely be unhappy with this arrangement, having previously said the deal with the Greens was “worth its weight in gold” when compared to the tribulations of running a minority government.

A return to minority status could prove problematic for the SNP. Long gone are the days of the “rainbow parliament” and Holyrood is now viewed as a very tribal legislature.

While first minister Alex Salmond enjoyed success working with the Scottish Conservatives. It seems unlikely this relationship could be replicated between both parties’ current crop of MSPs.

But there could be opportunities for the SNP in having to work more closely with other parties if they were dumped by the Greens. Progress on dualling the A9, for instance, could be expedited, with the help of Conservative politicians.

Some MSPs, most notably Fergus Ewing (above), would be delighted by this and it may assuage the fears of some who fear the Greens have dragged the Scottish Government away from “middle Scotland”.

This seems the least likely option but theoretically it could happen. If the Scottish Greens ditched the SNP, Yousaf may well decide that he would like to go back to the country.

He may calculate voters may take a dim view of the Greens for storming out of government and the SNP may have a story to tell about sticking to their guns in the face of left-wing pressure which may play well to some voters it does not reach as well as it used to.

However, given recent polls show Scottish Labour gaining on the SNP Yousaf may not want to roll the dice with the electorate quite so soon.

But if the Greens pulled out of Government he may be vulnerable to challenges such as no confidence votes and it is not clear whether he may have to be re-approved as first minister by the parliament.

Yousaf may not want to go to the polls but as the leader of a minority government, opposition parties can pull levers which could give him no other choice. 

Status quo

The option it appears the Scottish Government favours at present. A senior source told The National the Scottish Greens should “use the time and space between last week and their vote to decide their position in a dispassionate manner”. They added: “It’s important not to make the end of the BHA a self-fulfilling prophecy.”

It also appears they also view this as the most likely option, with another insider saying they “highly doubt” the Greens would depart government.

But in this scenario, anti-Bute House Agreement sentiment may become more focused in the SNP wing than the Greens.

Harvie and Slater (above) may feel under pressure to be seen to be doing more to extract wins from their partners in government – which may alienate some of the SNP’s right-wing even more than they already are.

Calls from figures like Ewing and Kate Forbes (below) to ditch the Bute House Agreement may grow if the Greens feel they need to bag more policy wins they can boast about to their members.

Whatever happens, we’re in uncharted territory here.

Coalitions in their various forms have basically held steady since the opening of the Scottish Parliament. There were no major challenges to the ruling Lib-Lab coalition for the first eight years of devolution from within.
