- Sainsbury's said on Wednesday retail like-for-like sales, excluding fuel, rose 0.2 percent in the 16 weeks to June 30, its fiscal first quarter.
- Total retail sales rose 0.8 percent, excluding fuel.
Sainsbury's, Britain's second biggest supermarket group which agreed a 7.3 billion pound ($9.7 billion) takeover of rival Asda in April, saw sales growth slow in its latest quarter, reflecting price cuts in a competitive market.
The firm said on Wednesday retail like-for-like sales, excluding fuel, rose 0.2 percent in the 16 weeks to June 30, its fiscal first quarter.
That was ahead of analysts' average forecast for a fall of 0.1 percent but below growth of 0.9 percent in the previous quarter.
"The headline numbers reflect the level of price reductions we have made in key areas like fresh meat, fruit and vegetables since March," said Chief Executive Mike Coupe.
"Our price position has improved and customers have responded well, resulting in a continuation of the improved volume trend we saw in the second half of last financial year."
Total retail sales rose 0.8 percent, excluding fuel.
Shares in Sainsbury's have risen 32 percent so far this year on the back of deal to buy Walmart owned Asda, which is currently being probed by Britain's regulator, the Competition and Markets Authority (CMA). The deal would see the combined group overtake Tesco as Britain's biggest grocer.
The CMA's probe is expected to be lengthy and Sainsbury's does not anticipate the deal being concluded until he second half of 2019.
Sainsbury's said on Wednesday it has agreed a financing package of 3.5 billion pounds for the deal.
"The market remains competitive. However, we have the right strategy in place and our proposal to combine Sainsbury's and Asda will create a dynamic new player in UK retail," said Coupe.
