LONDON - A much-loved British biscuit has fallen victim to the Brexit-linked slump in the pound, as McVitie's Digestives on Saturday said their packets will shrink. Packets of the quintessentially British brand will be cut from 500 to 400 grams this month, after the weakened pound ramped up import costs. "The rising cost of ingredients and changes in the exchange rates means it has become more expensive to bake our products," said Nick Bunker, UK and Ireland managing director of Pladis which owns the brand. Britain's decision in 2016 to leave the European Union led to a sharp drop in the value of the pound against the euro and dollar. The sweet wheaty biscuit is a British staple, often dunked into a cup of milky tea, and is sold internationally. "It would appear that nothing is safe from the effect of rising costs in a post-Brexit world," wrote The Times newspaper. The pro-EU campaign group Open Britain said: "This really takes the biscuit". While some saw smaller packets as a way to tackle obesity, others were not so enthusiastic. "Mr. Robert McVitie must be twisting in his grave," reader Ahmed Bayram responded on The Times website. In October 2016, Toblerone announced the triangular-shaped chocolate had shrunk over rising costs. Consumers have since complained of numerous companies selling smaller versions of their products. - AFP
