Sainsbury’s is gunning to become one of the UK’s top five clothing retailers as it expands its Tu fashion range.

Tu is currently seventh largest by volume, behind Marks & Spencer, Primark, Asda, Tesco, Next and Matalan, according to Kantar Worldpanel. It has a 3.3% share of clothing, footwear and accessories.

Luke Jensen, managing director of its non-food division, told the Telegraph that Tu can “definitely be a top five” brand over the medium term.

This week Sainsbury’s will launch its biggest ever Tu advertising campaign.

The ad, which breaks on Wednesday, features its summer ranges and is set to the soundtrack of At Last by Etta James and has the strapline “clothes you can’t wait to wear”.

The retailer wants to make Tu a household name, it said.

Jensen said: “Our aim is to double our non-food sales over a rolling four to five year period. So it is growing at 20% a year and clothing is a very important part.”

Tu is a £500m business. Earlier this year it announced a partnership with TV stylist Gok Wan to create a clothing range.
