Yesterday I wrote this blog speculating about Conservative motives for keeping the boundary review in play, even when the Lib Dems have signalled their determination to vote against the plan.
The Tories, I surmised, are desperate to sustain the project on life support, even when all vital signs have gone, partly in the hope that it might yet one day be resuscitated but also because postponing its final extinction gives Conservatives a bargaining chip in other negotiations.
I have since spoken to a senior source close to Nick Clegg who, while not disputing my analysis of Tory motives, wanted to make clear that, as far as the Lib Dem leadership is concerned, the boundary changes are finished. That is non-negotiable and if the Conservatives think otherwise they "don’t quite get it".
"The next election will be fought on the old boundaries," my source said. "They [the Tories] need to accept that we are deadly serious about that … We are not going to allow boundary reform."
As for the idea of scraping together a majority in the Commons with votes from Ulster Unionists and Welsh Nationalists, Lib Dems politely point out that there are Tory MPs who would rebel in a vote on boundary changes. The whole concept of driving the whole thing through with pork-barrel promises to minor parties, say top Lib Dems, smacks of desperation on the Conservative side as the realisation dawns that winning a majority next time will be very, very hard indeed.
It is worth noting also that the "mid-term review" of coalition policy, due in November some time, has been postponed until January. This is the project that was once going to be grand renewal of vows under the Steve Hilton-esque "Coalition 2.0" rubric but was downgraded to a more modest audit of progress so far on policy implementation and outline of future priorities.
I am confidently assured that the delay says nothing at all significant about the state of relations between the two parties and that it is simply a function of the fact that the Autumn Statement (due on 5 December) is more urgent and takes up too much time, so the sequence of the two events changed. That is perfectly plausible.
Still, if there is to be a chapter on political or constitutional reform in the mid-term review the two sides clearly need to be communicating a bit more effectively about those boundary changes.
