Booker CEO Charles Wilson described the wholesaler's 2010 performance as "good progress" at the release of its annual results last month, but the judges were blown away by another sparkling year from the cash & carry giant.
It's the second year in a row Booker has won the title and the judges said the wholesaler had "world-class management with a financial performance second to none".
Pre-tax profits rose a massive 25% to £71.4m, with sales up 6.2% to £3.6bn during the year.
The judges were also impressed by Booker's progress in all areas of its business. Tobacco, non-tobacco, fruit and vegetable and sales to caterers were all up during 2010, and availability also continued to improve.
Its symbol fascia Premier also reaped the rewards of its 2009 relaunch to become the UK's biggest symbol group by store number for the first time with nearly 2,600 stores. And the wholesaler's own-label range Euro Shopper also wowed the judges for new product launches and its growth from zero to £100m in sales in just three years.
The judges also singled out Booker's "accelerating momentum". It acquired fine food supplier Ritter-Courivaud and on-trade wholesaler Classic Drinks in November and is preparing to open two new depots in India following success with its first, in Mumbai, in September 2009.
