LONDON, Feb 4 (Reuters) - The proportion of British workers working solely from home rose to 36% in the week to Jan. 31, its highest since June when the country was emerging from its first coronavirus lockdown and up from 34% the week before, official figures showed. Spending on debit and credit cards, as measured via Bank of England CHAPS payment data, was 32% below its level in February 2020 versus a 35% shortfall a week earlier, the Office for National Statistics said on Thursday. The Bank of England is due to release new quarterly economic forecasts at 1200 GMT. (Reporting by David Milliken Editing by William Schomberg)
