Whole Foods Market, which is set to open its first UK store in London next year, has warned that it expects slower sales growth next year.

Releasing its full-year results to 24 September, John Mackey, chief executive of Whole Foods Market, said that 2007 would "be a transition year", with same-store sales growth of 6 to 8%. It has posted double-digit growth for the past three years.

The retailer reported a 50% increase in full-year net profit to $203.8m, on sales up 19% at $5.6bn.
