(Reuters) - Britain’s annual economic growth rate could be in double digits a year from now, the Bank of England’s chief economist Andy Haldane wrote in a Daily Mail column published online late on Thursday. Economic recovery should be "one to remember, after a year to forget," Haldane wrote here. The central banker predicted that British households would have amassed “accidental savings” of up to a massive 250 billion pounds ($345.30 billion) and that there would be a spending boom once COVID-19 restrictions are lifted in the country.
