Hmm, you seem to have neatly airbrushed out the Labour government’s catastrophic handling of financial sector regulation ahead of the financial crisis, which required the UK to make the largest fiscal intervention of any G7 economy as the crisis hit, and effectively forced the government act as a guarantee for all interbank lending during the period.
You also appear to have forgotten the structural deterioration of the fiscal position in the run up to the financial crisis - they inherited a surplus and ran up a significant deficit, again before the crisis hit - which led Gordon Brown to conveniently rewrite his fiscal rules.
Just three months before the coalition government came to power, the government financing requirement stood at 13% of GDP, an unprecedented figure outside of wartime and the peak of the pandemic. But, of course, the Labour government had nothing whatsoever to do with the austerity that followed and it’s just the Tories fucking up isn’t it?
