I don't know how old you are, but back then 2008 when we bailed out the banks our deficit was huge.
In other words the Torries was left with a credit card bill of an ungodly amount and gap of funding of 10% for the bill, when Labour talk about a black hole - it's not a black hole it's a gap, because it's Q3 of the financial year meaning the end of year isn't even over.
I'm sure Labour will fix a lot of things, but the lies they are using isn't a good look so early.
By the way that pandemic jump down the year after is very interesting, because it an Indicator of quantitative easing (printing money) which in turn lead to Inflation because of the supply and demand of money we had more of it.
