The total weight of treats in festive boxes of chocolates is shrinking, it has emerged.

Cadbury’s stocking and Freddo selections are smaller this year than previous years – but prices have remained the same.

While McVitie’s Victoria and Family Circle biscuits boxes have also shrunk.

A spokesman for the company which owns Cadbury’s told The Mirror newspaper: “We have updated the range available in our selection boxes. This meant the weights of our products changed and while some increased in size, some decreased but the number or ­remain the same.

“The retail price has therefore remained the same.”
