As in the US with Harris investment in America vs Trump cuts there is a distinct difference between the Tory spending plans that allowed capital spending investment in the economic future of Britain to decline from 2.5% to 1.7% of GDP over 5 years to 2030. Rachel Reeves, Britain's finance minister, says the government will adopt a new rule that changes the way it measures debt- public sector net liabilities as a percentage of GDP is the new fiscal rule. What it does is free up 50 billion pounds Britain badly needs to invest in things like climate change action, education, and other needs of the economy that will brighten Britain's prospects in the future. 

“If we continued on that path, we would be embracing a path of decline. The real debate now in British politics is whether you are on the side of investment or on the side of decline. I don’t want to see public sector net investment as a share of our economy decline in a way that is currently set out. Under our current fiscal rules, we would not be able to reverse that path.”

The stability rule goes with this that says strictly this money will not be used for tax giveaways, and not for public sector pay deals or the day to day functioning of government. In addition th government will borrow 25 billion pounds to  keep 30 billion pounds of headroom so that debt will keep falling over the first term of this Labour government.
