The average household had £7 less disposable income to spend a week on leisure and entertainment in February against a year ago, according to Asda.

The chain's monthly income tracker found the average UK household family had £133 to spend on leisure and entertainment compared with £140 in February 2007.

Food and non alcoholic drink prices had increased 5.6% on a year ago, while spending on essentials rose 5.2%.

"In light of February's data our priority must be to keep inflation at bay,” said Asda CEO Andy Bond. “The challenge for us and our suppliers is to ensure that we don't pass on unnecessary cost increases to customers."
