Britain’s gross domestic product tumbled 5.7% from a year earlier in March 2020, following a downwardly revised 0.2% growth in the previous month. The government ordered in mid-March a shutdown of much of the country to stop the spread of COVID-19, forcing many businesses to close and people to stay at home. On a monthly basis, the economy contracted 5.8%, the biggest monthly fall since the series began in 1997.
