There's reaction from the IEA, but not a great deal that I can see on other think-tank websites. Mark Littlewood, its Director General, says that the downgrade is "a wake-up call for George Osborne" (and see the fifth tweet above, too).
Nothing either, as I write, on the websites of the CBI, TUC, or the IOD. So for the record there's a mix of reactions above, mostly from the centre-right, including Ryan Bourne of the CPS and our own Andrew Lilico, from today and yesterday.
