Tesco said it was taking "another step in the right direction" after its UK like-for-like sales fell by 1.3% in the first quarter of the financial year.
The supermarket giant the results were an improvement on the 4% fall in the same period last year and a 1.7% decline in the previous quarter.
Tesco chief executive Dave Lewis said: "Whilst the market is still challenging and volatility is likely to remain a feature of short-term performance, these first quarter results represent another step in the right direction."
