Should a party’s annual conference make binding policy, and what role should an ordinary party member have in those decisions? Scotland’s main political parties appear to have come to very different answers to this question, which I will try to sum up below. Please bear in mind that I have only got direct experience of my own party in this respect, and will be happy to correct any factual errors below.

At one end, the Scottish Conservatives adopt an approach to policy-making which does not include any notion of internal democracy. There are no votes on policy matters at conference, even token ones, although early in the Cameron era his Built To Last document was submitted to a vote. Instead, the leadership determines policy: typically just the leader plus his or her kitchen cabinet. In this sense therefore, the Tory system is relatively close to that used by the Workers’ Party of Korea, who rarely bother with the rubber-stamp assembly beloved of other notionally leftwing personality cults. It’s at least honest, and to be fair, since 1998 the Tories have also let the membership choose their leaders from a shortlist of two by one member, one vote. This is clearly progress over the old approach – where MPs only got a vote – or the even older version – a leader “emerged” from the “magic circle”: i.e. it was carved up out of sight in a way that must have been great fun for those who regard politics as a full contact bloodsport.

Next along this sliding scale: Labour. Their procedures used to be highly democratic, including the formal setting of policy through motions such as the composites beloved of union bigwigs and loathed by the Millbank Tendency. This is all basically over now, with the leadership now setting all policy, not even the Blairite National Policy Forum. Some of the changes are relatively recent: until 2007 branch parties and trade unions could bring policy motions for a vote, even if the results would then be ignored by Labour Ministers. Having mentioned leadership above, personally I also deplore the way Labour allows people to join several “socialist societies” and unions and get several votes for a new leader, not to mention the way MPs both sift the candidates then get massively disproportional say in the outcome.

Then the Lib Dems. They have picked a particularly bizarre point on the spectrum from Stalinist control through to radical democracy. As I understand it, their conference is open to all members, all of whom can vote and bring forward motions. The problem is they mean nothing, especially when Lib Dem Ministers have got some selling out to do. This week the issue was so-called “free schools”, discussed here previously by Jeff. As the Lib Dem proponent of the motion said, “Just as the supermarket drives the corner shop out of business, so it will be with schools.” Danny Alexander, described by one Twitter wag as tree-promoter turned economics expert, then declared it would make no difference to policy. The same used to apply to Scottish Lib Dem conference when they were in government here. The membership said that GM crop trials should stop. Ross Finnie pressed on regardless. Curious. Not particularly liberal nor notably democratic.

Although it was put to me that this blogpost was designed to make Greens look good, the brief research I’ve done does show the SNP joining us at the actually democratic end of this spectrum. I must admit I know less about the SNP’s procedures, but I do know that, like the Greens, their conference does formally set policy, with members and branches free to bring motions. I also can’t find an instance of the leadership simply over-ruling them, although Mr Cochrane, the Last Black-Hearted Unionist, has got one. The party’s leadership procedures are posted online in their entirety, and seem pretty hard to fault. Like us, it’s one member, one vote, no special treatment for MPs or interest groups.

The open question is not one of principle, though – obviously it’s hard to make a principled objection to internal democracy. But are parties with actually democratic procedures more likely to survive internal tensions and evolve, or can that internal democracy make it harder to respond to changing circumstances? Does Labour’s “democratic centralism” actually help them more than they pay in demoralised activists, unable even to slow a swing to the right? Those decisions surely weren’t taken simply for self-interest: Peter Mandelson or someone else must have concluded that the open expression of democracy was more damaging than the alternative. My sense is that that move was wrong both strategically and in principle, but I don’t have any evidence for that view.

And is going into government something which ought to change a party’s approach? Did the Lib Dems stick to the policy set by conference except where it restricted Lib Dem Ministers’ activity? Will Labour return to a more democratic approach now they’re in opposition across the country? Have the SNP really managed to keep internal democracy while running the Scottish Government? There seems little point letting the membership set policy only when you’re in opposition, rather than when you might be able to make real change.

As a press officer for a democratic party, I certainly see one downside of the radically democratic approach, not that I’d change it. Any radical new policy development the party makes can’t be unveiled dramatically in March or April of an election year. It must instead be decided in public at our autumn conference. If only there was a way we could agree any policy changes democratically but still keep them under our hats until we could publicise them as effectively as possible.
