UK inflation is expected to have improved slightly in May as oil prices recover, DigitalLook reported. The consumer price index for May, released on Tuesday, is forecast to rise 0.4% year-on-year, up from April’s 0.3%. Core CPI, which excludes food and energy prices, is projected to have increased by an annualized 1.3% in May following a 1.2% gain in April. Headline inflation remains well below the Bank of England’s 2% target due to ongoing falls in energy and food prices.
