Debenhams has unveiled plans for its biggest ever Sale with thousands of products up to 70 per cent off across its stores.

The Sale will start at 7am on Boxing Day in its shops and launch online on Christmas Day. It will reduce prices on the largest number of products in its 219-year history.

Debenhams deputy chief executive Michael Sharp said: “Pre-Christmas we were helping our customers cut the cost of present buying by offering them value for money on gift solutions for friends and family. Now we want to make sure that they have the opportunity to treat themselves at a time when they need it most.”

Marks & Spencer will also be launching its Sale online on Christmas Day, with many of its stores opening at 6am to kick off its Sale in stores on December 27.
