John Lewis said its revenue rose last week even though the UK saw widespread looting and rioting, as customers turned to the web.
Sales at its department stores increased by 2.9 per cent to £52.9m in the week to 13 August. Sales excluding VAT were up 1.3 per cent.
The department store chain said: "John Lewis online managed to pick up the customers that couldn't or didn't get to our shops. So considering the events of last week on our streets and in the financial markets it was a solid performance."
