Budgens has been the official retail partner for the event for the past seven years, but The Grocer has learnt it will not sponsor the fortnight's 10th anniversary event next year.
Budgens' contract came to an end this year and the retailer had decided not to renew it, said Alexia Robinson, founder and organiser of British Food Fortnight. "The event has outgrown Budgens," she said. "British Food Fortnight has grown massively since the company first came on board as a sponsor seven years ago".
The event's organisers were currently in talks with a number of large retailers regarding the sponsorship, she said. "For such a large, national event we need a large sponsor," she said, although she thanked Budgens for its support.
Many of the independent retailers trading under the Budgens fascia had also run special British promotions, tasting and special offers during the event.
Musgrave Retail Partners GB, which runs the Budgens symbol, would not comment on why the sponsorship had not been renewed. "Budgens was involved in a fixed-term sponsorship with British Food Fortnight that has now ended," said a spokeswoman.
Next year's event will take place between 17 September and 2 October and the 2012 event has been scheduled to run at the same time as the London Olympics.
