In its adjudication published today (25 September), the ASA said that Asda’s advert comparing the price of 7,564 of its products with Tesco was misleading.


“There was no firm evidence one way or another to suggest that Asda or Tesco was cheaper,” a spokesperson for the ASA told just-food.


“The ASA says there must be documentary evidence to support such claims. While Asda did have documentary evidence, Tesco then produced evidence to suggest that they were cheaper. We upheld the complaint because we cannot favour one set of evidence over the other and we needed to see clear proof to support Asda’s claims.” 


The ASA said that Asda referred to online prices rather than those in stores and that the timescale over which the comparative figures were collected and advertised was misleading.
