Booker's revival has continued with another strong set of results.

Preliminary results for the year to March 26, 2010, saw sales rise by 6.5% to £3.4bn, with operating profit up 15.2% to £66.6m.

Sales to Premier retailers were up 13%, and the company aims to recruit another 1,000 retailers into the symbol group in the next three years.

After years of heavy debts, the company now has a net cash position of £7m. Further investment will be made in the group's delivery network in the next financial year, and 20 more cash and carry branches will be converted to the Extra format.

Chief executive Charles Wilson maintained that the company would continue to focus on its core business. He said: "We are not looking to build more new depots, but instead to concentrate on doing a better job for our customers."
