Cash and carry group Booker saw sales boosted by its recently acquired Budgens and Londis chains as they helped offset the impact of falling food prices and a hit to consumer demand before the Brexit vote.
The group, which supplies 1.3m independent retailers, said like-for-like sales excluding tobacco and the Budgens and Londis brands fell 0.7% in the 12 weeks to June 17 after many customers reported weak consumer demand.
Sales were also impacted by ongoing food price deflation amid a fierce supermarket price war.
But total group sales including its two new brands surged by 11.7% excluding tobacco, and chief executive Charles Wilson said Budgens and Londis made a "solid contribution".
Tobacco sales remained under pressure from the ban on small stores displaying products, slumping by 7.7% in the quarter on a like-for-like basis.
The group completed the £40m (€46.87m) takeover of Budgens and Londis from Irish food wholesaler Musgrave Group last September.
The deal saw it add 1,630 Londis stores and 167 franchised Budgens outlets to its existing 172-strong chain.
Booker also owns Makro, which it bought for £140m (€164.09m) in 2012, as well as brands including Family Shopper and Premier.
The group hopes the Budgens and Londis deal will boost its might in a difficult retail market, which has seen intense price cutting due to the growth of discounters Aldi and Lidl.
