You clearly haven’t a clue what you’re talking about, and neither seemingly does Starmer. Ignorance is I’m afraid no excuse for the amount of nonsense and bluster you post. Starmer should know better, at least.
The OBR frequently changes its productivity assumptions, and the latest revision is not especially large relative to the history of these.
To quote paragraph 1.5 of the OBR document explaining the recent change in productivity assumptions;
‘We have made several previous downward revisions to our trend productivity forecast in response to shocks and the growing period of weak productivity growth since 2008. The 0.3 percentage point revision we have made to medium-term productivity growth is significant, but not as large as the 0.5 percentage point revision we made in November 2017. Comparing the forecast change in five-year cumulative trend productivity growth, there are five other EFOs where we have made downward revisions of a similar or larger magnitude.’
Again, you are misinformed, and so is Starmer. Given that Starmer was only speaking today in an attempt to save Reeves after she’s been found to have lied again, one would have expected him to be in full knowledge of the facts surrounding the OBR’s forecast revisions, what these entailed and when the Chancellor was informed of these changes.
But sadly, he isn’t. I think this neatly illustrates the amateurish nature of this government and how they believe they’re still able to mislead the public. Thankfully, not all of us are as gullible as yourself.
