SHOPPERS trying to stock up on baby milk were surprised to see a sign saying they could not purchase more than two tubs of formula at a time due to a ‘national milk shortage’.

The signs were on shelves in Boots in The Mall, Blackburn.

A spokeswoman from Boots said: “Our Blackburn store was following manufacturer’s guidelines after Danone asked for a restriction to be put on their infant milk.

“However, the restriction should have lasted from April to October. It must have been forgotten about.”
