Inflation has dropped 2.1% in October to a two-year low, as the Prime Minister meets his "top priority" of halving inflation by the end of the year.
The data, from the Office of National Statistics (ONS), is at its lowest as the increasing cost of gas and electricity slows down.
Rishi Sunak pledged to halve inflation to below 5.4% at the start of the year, a goal that's been reached comfortably with ONS figures showing inflation dropped o 4.6% in October.
The drop was always expected in October -albeit it was more than the City expected - as Ofgem lowered the cap on household bills to £1,834, after sitting at £2,500 last year in the wake of Russia's invasion of Ukraine.
Grant Fitzner, Chief Economist at the ONS, said: "Inflation fell substantially on the month as last year's steep rise in energy costs has been followed by a small reduction in the energy price cap this year.
"Food prices were little changed on the month, after rising this time last year, while hotel prices fell, both helping to push inflation to its lowest rate for two years."
Posting on X, the social media site formerly known as Twitter, Sunak said: "In January I made halving inflation this year my top priority.
"I did that because it is, without a doubt, the best way to ease the cost of living and give families financial security.
"Today, we have delivered on that pledge."
