You might want to have a look at what Gordon Brown did to government debt levels.
I suppose you believe the lie about the note, 'there is no money left' David Cameron was waving it around for all to see and it was championed by our largely right wing press as proof positive Labour couldn't manage the economy responsibly.
That note was nothing more than a traditional self deprecating measure of performance left by the outgoing minister to the incoming minister as a light hearted joke, started by Winston Churchill in the 1920's, and carried on in that vain until Cameron took office in 2010.
'Sorry, old bean, I've made a bit of a mess of things. Have fun sorting out the mess'.
Cameron admits in his autobiography that joke of a note note was deliberately promoted to underline his desire for austerity, an action widely condemmed at the time as unnecessarily cruel to the poorest in society, and which has subsequently cost hundreds of thousands of lives.
Austerity has reduced the services we once regarded as reliable, such as appointments with doctors, needing an ambulance when required, a Police response to a crime, an operation to fix a worn out knee or hip, to almost zero.
There are 7.5 million people stuck on waiting lists for NHS treatment, NHS dentists are no longer available, we have crumbling roads full of pot holes, schools that are falling down, neither of which this government have any plans to restore. We have a declining age expectancy, all a result of austerity, just so some rich people can salt their money away in tax havens
What more can I say, other than the national debt was far lower when Labour were last in power. Everything worked as expected when needed, but billions have been wasted on track and trace that delivered nothing
What I will add to this though, is the financial crash in 2008 was nothing to do with UK government policy at the time. It was the sub prime market in the USA that folded. It had huge repercussions throughout the world, and the actions taken by Alistair Darling as chancellor and Gordon Brown as Prime Minister are regarded throughout the world as saving the worlds banking systems from collapsing.
£100B has been wasted by this government on track and trace, supporting the financial markets after the disasterous budget Liz truss imposed on us, and supporting the pound after the brexit referendum result, a far higher amount than Darling and Brown spent on supporting the banks in their hour of need which was totally out of their control.
