Meat and fish traders have been given the green light by the House of Lords to sell their wares for the first time at London's New Covent Garden market.
The market, which is a leading centre for specialist catering distributors, had only been allowed to host the sale of fruit, vegetables and flowers in the past.
Last week the House of Lords overturned a ruling from the Court of Appeal that supported opposition to the move to sell meat and fish at Covent Garden from the Corporation of London.
Originally the Department for the Environment, Food and Rural Affairs had rubber-stamped the decision to add meat and fish to the market in 2003.
Baroness Brenda Dean, chairman of Covent Garden Market Authority, said: "This is an important breakthrough for London's thriving restaurants, caterers and food retailers."
Jeff Rooker, minister for sustainable farming and food, said customers would now be able to meet all their needs at a "one-stop" shop under one market roof.
