But before looking at that particular policy, the Unionist devolution double standard and lack of convincing rationale was brought into focus this week on Newsnicht, when former first minister Henry McLeish proffered the following waffle in relation to interference from Westminster Labour into the party's policies at Holyrood:
I [had a meeting with Iain Gray] only a week ago...and I was very impressed by the desire on [Scottish Labour's] part to be looking at policies...which are in tune with the needs of Scotland but in a way reflect what is happening throughout the United Kingdom, so in that sense I remain very positive that they are thinking, that there are ideas developing, but what is really important here...is that we need the two - Scotland and Westminster - to be working in tandem. I can see more potential coming from Ed Miliband in relation to that, and if that happens then that would be a significant step forward.All of which sounds a bit like Iain Gray's 'same but different' approach to Westminster/Holyrood interaction last time round. And dual MP/MSP Margaret Curran made similarly unconvincing noises on this week's Newsnicht item in relation to why she dumped Holyrood to stand for Westminster.
Thus when Westminster Labour pokes its nose into Holyrood business that undermines the case for devolution, and when Holyrood Labour is allowed to do its own thing then this undermines the rationale for a UK-wide Labour movement. And the Labour turf wars help to disguise the fact that Unionism and devolution are fundamentally incompatible, and thus Holyrood smacks more of empire building, jobs for political pals, and as an electoral sop to head off the independence impetus (albeit perhaps misfiring, but that's another debate) and exploit the different electoral demographic north of the border.
And this week's living wage proposal - like Calman's proposed devolution of national speed limits and recent tensions concerning policies to tackle excessive alcohol consumption - underlines the hypocrisy. Why does the Labour Party think Scottish workers should enjoy better basic rights than those south of the border, particularly when the cost of living up here is no doubt less on average than it is down there, particularly as regards London and the south east of England.
After all, Labour admirably implemented the National Minimum Wage across the UK and increased it during its term of office, but if a further augmentation - which I wholly agree with - is deemed necessary for Scotland, then why didn't Labour just significantly increase the NMW across the UK when in power? What's peculiar about the workers of Scotland that they deserve more favourable basic rights than workers of the UK as a whole?
And, of course, the second hypocrisy in relation to Iain Gray's proposal is that the living wage would only apply to public sector workers, since the NMW is a reserved power, thus Holyrood has no say over conditions of employment in the private sector (and I can't recall Calman proposing to devolve such powers), and his hope that pressure could be exerted to extend this more widely in the Scottish economy is unconvincing.
Thus to that extent the living wage would be a bit like the St Andrews Day holiday - which as I recall was only to apply to the public sector - and will therefore seem a further kick in the teeth for people employed in the private sector, particularly in view of the increasing perception that the public sector seems featherbedded in comparison with those more exposed to the rigours of the labour market.
Of course, this characterisation often seems unfair - the best rewards can be found in private enterprise, while the need for a living wage in the public sector demonstrates the often paltry recompense for those working there - but Scottish Labour's proposal represents self-evident hypocrisy at two levels, and would also exacerbate the perception of an increasing public/private divide in terms of conditions of employment, and would additionally aggravate the English perspective of Scotland as a whole being pampered by its subsidised reliance on the public sector.
Holyrood was never going to be conducive to UK or Unionist party cohesion, and the further devolution of powers would merely underline that. Which has always, of course, been to the SNP's benefit.
On the other hand, with Holyrood's PR system proven to have delivered a succession of weak governments unable to implement much in the way of distinctive Scottish policies, then to that extent the Unionist fissure is probably not as obvious as it could be, which was perhaps the rationale for the voting system.
But at a very basic Unionist level, and in view of the havering McLeish and Curran et al, the very point of devolution seems hard to fathom.
