Sainsbury's has reported an eight per cent rise in underlying profit to £332m.
The retailer said its share of the market had risen to 16.2 per, from 15.9 per cent.
Like-for-like sales, which strip out the effect of store openings and closures, rose by two per cent.
The strongest growth came, not from food, but from sales of items such as homewares and clothing.
Sainsbury's Bank is also increasing customer numbers, which rose by 5 per c. 28 weeks to the beginning of October.
