LONDON (Reuters) - British consumer spending fell over the past week and the proportion of people on furlough and who are working exclusively from home increased, as the country remained in a coronavirus lockdown, official figures showed on Thursday. Debit and credit card spending - as measured by Bank of England CHAPS payment data - was 28% below its level in February 2020 during the week to Feb. 11, representing a greater shortfall than the 24% shortfall reported the week before. Businesses said 20% of their staff were on furlough between Jan. 25 and Feb. 7, up from 18% two weeks earlier but below the peak of 30% recorded in June during the first lockdown, the Office for National Statistics said.
