I'm generally inclined to believe what the Bank of England says over the Government, but this is an important thread on inflation. I don't know if it's all correct, but it is an explanation of why the BoE's policy isn't working.
Getting your model wrong is one thing. Getting your policy wrong is something else when that policy has real-world implications, and they are the opposite of what you intend. That, I suggest is what is happening right now. Interest rate rises are creating inflation.
