Tesco is braced for another fall in quarterly sales in the UK when it announces its latest results on Wednesday.
Sales at the supermarket giant are expected to be down by around 2% in the first three months of 2012
Profits across the group will rise by between 2% and 3% to around £3.8bn, according to City expectations, buoyed by strong performances outside the UK.
Chief executive Philip Clarke will use the announcement to outline a series of measures designed to reinvigorate the UK business, with up to £400m earmarked for investment improving stores.
His strategic blueprint is expected to include a major ramping-up of Tesco’s online operation, with the click-and-collect service being extended across hundreds more stores.
In comments made over the weekend, he described the investment plan as “not a radical change of direction, but a radical change of pace”.
