OK I'll add my two penneth. The debt level, of the country, was smaller when Labour left office. That's a fact. And, before I'm accused of being a myopic "Liebour" supporter, that's, simply, not the case. I don't think you can trust many politicians.
Despite all the austerity measures, we now have a a national debt that is much bigger, and runs into the trillions. So, you have to ask yourself, what is all this austerity for? It's got to be an ideological crusade to increase the pressure on the 99% of the population, whose taxes are no longer required;instead the Bank of England prints endless amounts of fiat currency, and this is given to banks at, almost, zero interest rates to gamble on high frequency market trading. This is why nobody(public or private) gets a pay rise - they don't need to take more tax; it's just a case of printing more money. Meanwhile, the rest of us have to use use payday lenders, with rates as high as 4000%.
So, I think you can blame the banks and the Tories. And that is based on sound facts.
