The UK economy saw its biggest contraction since 1979 in early 2020 as households slashed their spending, according to official data that included the first few days of the coronavirus lockdown.
UK gross domestic product dropped by a quarterly 2.2% between January and March, the Office for National Statistics (ONS) said.
That was below the median forecast in a Reuters poll of economists for a fall of 2%.
British Prime Minister Boris Johnson will set out his plan to speed up the British economy's recovery later today when he will promise to fast-track £5 billion of infrastructure investment.
Britain's economy may have contracted by 20% in the first half of 2020, the Bank of England said earlier this month as the full effects of the lockdown hammered most sectors in the three months from April to June.
The Bank of England has said the slump in the economy this year could be the worst in three centuries.
Today's figures - which build on previously released data for the first quarter - showed a surge in household saving as their spending collapsed by the largest amount, in cash terms, since records began in the 1950s.
"The lockdown of most businesses on March 23 meant that households were unable to spend even if they wanted to," said Thomas Pugh, UK economist at Capital Economics.
He added that it will take the economy until 2022 to regain its pre-crisis level.
The household savings ratio shot up to 8.6% in the first quarter from 6.6% at the end of 2019.
The ONS has previously estimated that Britain's economy shrank by a record 20.4% in April from March but there have been some signs of recovery more recently.
New figures today also showed that Britain's current account deficit widened by more than expected in the first three months of 2020.
The balance of payments deficit - a long-standing concern for investors because it leaves Britain reliant on foreign inflows of cash - grew to 21.1 billion pounds ($25.9 billion) in the first quarter, compared with a median forecast of 15.4 billion pounds in a Reuters poll of economists.
Stripping out volatile movements of gold and other precious metals, the current account deficit narrowed slightly, the ONS said.
