UK retail giant Tesco has launched a week-long round of half-price cuts on hundreds of 'party food' items.

This weekend sees the beginning of the "party food season", the retailer said today (11 December). Tesco said it has cut prices on items including king prawns, smoked salmon, pizzas and Champagne.

"This weekend we are expecting party food to be one of the most popular items in our stores with millions of people wanting a fuss free evening in order to settle down on the couch and be glued to the TV for the grand X Factor final," said Tesco senior buying manager for convenience foods Simon Williams.

Williams said, with demand for "ever exotic party snacks" rocketing over the last two Christmases, the retailer has this year doubled its range.

The retailer recently launched several new lines including chicken fajitas, BBQ ribs, Hoisin duck rolls, breaded sticks and pops, and said it is now developing more lines for next year.
