From Toblerone to Marmite, many of our favourite brands have been caught in the fallout from the Brexit referendum. Toblerone reduced the size of its chocolate bars and faced a revolt from outraged shoppers. The chocolate manufacturer blamed the change on rising costs. A Brexit price row led to a standoff between Tesco and Marmite. And these are by no means the only well-known products to be affected by the vote. For Dispatches, Harry Wallop, who first broke 'Marmitegate', trawls our supermarket shelves to reveal what other goods have been affected by 'shrinkflation', and the marketing tactics producers use. He examines how much prices have increased since Brexit, and the clever promotions used by the supermarkets. The programme investigates how leaving the European Union and the imposition of import taxes could affect the cost of our shopping and whether some of our favourite goods could even disappear altogether.
