LONDON (Reuters) - Spending on payment cards in Britain last week rose to 100% of its pre-pandemic level of February 2020, up from 95% a week earlier, data showed on Thursday. Separate figures from the Office for National Statistics showed output-per-hour worked, a measure of productivity in the economy, inched up by 0.1% in the second quarter, leaving it 1.7% above its average level in 2019. Economists say productivity data are likely to be distorted by the effects of the pandemic. Reporting by Andy Bruce; Editing by William Schomberg Our Standards: The Thomson Reuters Trust Principles.
