Wispa has become the latest chocolate bar to shrink down in size, in an effort by Cadbury to keep bars below 200 calories.
Wispas will now be 7% smaller than its previous size and have 10 fewer calories - but are still being sold at the same price.
Two years ago, the brand cut the size of four of its most iconic chocolate bars - Curly Wurlys, Fudge Bars and Chomps.
A spokesperson told the Daily Mail that the move was made in line with the company's policy to help tackle obesity and reduce multipack calories to 200kcal.

However, industry experts also believe the size reduction is down to soaring demand for cocoa driven by decreased crop yields as a result of climate change.
