A roadblock to even more debt?

A snippet from the Times report on Brown’s “building programme” for council houses:

Mr Brown has the support of Margaret Beckett, the Housing Minister, in pushing through new regulations, according to government sources, but Alistair Darling, the Chancellor, is said to be resisting proposals that could add billions of pounds to public debt.

If you remember, there were numerous reports of tension between PM and Chancellor over debt ’round PBR time.  Of course, nothing may come of it – and it certainly hasn’t done much to restrain our eye-watering levels of public debt – but the idea that Darling is in some way a roadblock to Brown’s plans will surely fuel the ‘Cable for Chancellor’ speculation.
