Lidl hailing the best ever Christmas in its UK stores
Lidl, which has 39 stores in Northern Ireland, has claimed it was the "fastest growing supermarket" over Christmas after booking record festive sales.
The German chain said sales rose 16% in December as it experienced its highest ever footfall.
December 22 marked a record trading day in Lidl UK's history, the group said, while the week before Christmas was its "strongest ever".
However, it did not give a breakdown of like-for-like sales, again ignoring an industry benchmark used by its peers.
There was no seperate information on store performance here.
Among Lidl's best selling products was its Birchwood Farm whole fresh turkey, which contributed to a 10% increase in sales of the bird. Total fresh meat and poultry sales grew by 17%.
Tesco will reveal details of its Christmas performance today.
