The pair's responsibilities will be overseen by MD of non-food Luke Jensen while the grocer searches for replacements. Non-food growth is a key plank of chief executive Justin King 's strategy. In its interim results in November, he said non-food was growing at three times the rate of food and the supermarket was now the 10th largest clothing retailer by volume. King wants to double the size of the non-food business within five years. The grocer is rolling out its large-scale stores, at 100,000 sq ft, which have larger non-food areas, and pushing non-food online. Earlier this year, Jensen told Retail Week that "non-food is centre stage for Sainsbury's" and the supermarket was "playing catch-up in terms of space". One commentator said the loss of the two directors would leave gaps in Sainsbury's buying and product expertise, and while Jensen is "great strategically" the grocer needed to get in some people who really understood product.
