These include a new range of confectionery designed for children, a 40-line chilled party food range, a range of Swiss chocolates and a selection of fish starters and alternative festive desserts.
It is also introducing 70 Christmas specials on its premium label, The Best.
A re-launch of the range is planned for February.
