Clothing retailer Next has raised and narrowed its guidance range for full-year sales, triggering a 2.4% rise in the company's shares on Tuesday.

The company said: "Sales are currently ahead of the 5.5% - 9.5% full year growth guidance we gave in April. We are therefore raising and narrowing our sales guidance range for the year to 7% - 10%."

In a trading update Next reported that its first-half sales rose 10.7%. 2.4% came from the opening of profitable new space, 7.5% came from its store sales rising and 16.2% with its online business, Next Directory.

At the beginning of this year Next also saw its annual profits overtake Marks & Spencer for the first time.
