Tesco will wait for the police to conclude any official investigation before taking a stance on the News of the World phone hacking scandal.

The supermarket is a regular advertiser in the News International title and has come under pressure from consumers to boycott the paper this weekend.

The row comes amid claims that a News of the World investigator hacked into the voicemail records of the missing teenager Milly Dowler, who was subsequently found murdered.

“We know that you have a lot of questions surrounding recent News of the World allegations,” Tesco said on its official Facebook page.

“These latest allegations will cause huge distress to a family which has suffered enough. It’s now a matter for the police; like everyone, we await the outcome of their investigation.”

A website has been set up to put pressure on News of the World advertisers, enabling Twitter users to contact companies directly, urging them to reconsider their advertising spend. WH Smith is also targeted as a major stockist of the title.
