There is a lot of talk in the UK of tax cuts, being proposed by the majority of candidates trying to becoming PM.
However the UK national debt is huge. Cutting taxes when the debt is so huge seems odd if not reckless.
UK general government gross debt was £2,382.8 billion at the end of 2021, equivalent to 102.8% of gross domestic product (GDP)
The reason for the huge debt is that the UK government runs at a deficit, in other words it spends more than it earns in taxation.
The debt is unstainable.
