Gillette recorded a 10% increase in sales value for the 52 weeks to June 19, which would have placed it in the same position as in last year's Biggest Brands table.
The sales increase for Gillette makes it one of just five in the top 20 to record double-digit percentage rises, and the only non-food brand to do so. The fastest-growing brand in the top 20, following the revised figures, was Warburtons, with growth of 16%.
Tryton Foods-owned Aunt Bessie's, which entered the frozen ready meals and vegetables categories during the period, makes its debut in the list of top 50 brands.
McCain was mistakenly ranked at number 23 in the 2005 listings, owing to the omission of sales data for its Microchips product toward its total value.
In fact, the frozen-food manufacturer is the UK's 19th-biggest supermarket brand by value. Marketing's table and accompanying commentary on its performance was based on an inaccurate figure of a - 10% change in sales value on 2004.
The correct figure is a 4% rise, moving McCain up the table by four places.
McCain spent 拢3.75m on a campaign celebrating the 25th anniversary of its Oven Chips last year.
The company is the 190th-biggest advertiser in the UK, according to Nielsen Media Research, spending 拢9.44m in the 12 months ending June 2005.
