The Covid-19 pandemic led to the sharpest fall in UK output in over 300 years in 2020, causing it to decline more than any other major economy, according to updated official figures.
A report by the Office for National Statistics (ONS) showed gross domestic product (GDP) declined by 11% in 2020.
According to historical data hosted by the Bank of England (BoE), this was a larger drop than any of the ONS's previous estimates and the largest since the 'Great Frost' of 1709.
Though there was a sharp rebound in the British economy last year and it recovered to its pre-pandemic size by November 2021, fast-rising inflation has led to a warning from the BoE that the economy is likely to slip into recession later this year.
The ONS had previously estimated that Britain's output in 2020 had fallen by 9.3%, the largest drop since just after World War One and the greatest fall in the Group of Seven.
The latest revision makes the decline in UK GDP greater than Spain's, which fell by 10.8%.
However, the ONS cautioned against direct comparisons with other countries as most, except for the US, have not yet undertaken the same kind of comprehensive revisions as Britain.
The revision to GDP reflects lower contributions from healthcare and retailers than previously estimated.
The ONS will release updated growth figures for 2021 and the first half of 2022 on 30 September.
