Two things about this error are interesting:
Firstly nobody is picking up on it sufficiently and giving it the weight it deserves in terms of explaining why the BoE later needed to step in to the gilt markets (28/9). We are told this is because of the tax cuts announcement, but we are not told that a more substantial contributory factor was the failure to only raise interest rates by 0.5%.
Secondly as a result of the first failing, the blame is all being placed with the government for the tax cuts, and no blame is being attributed to the BoE, which is completely wrong (and dangerous).
Nationalise the Bank of England and do it as soon as possible.
