Tickled Pink has been supporting Breast Cancer Campaign and Breast Cancer Care for over 17 years, and over that time they've raised £40 million for the organisations. Now they're on a mission to raise another £5 million, and Diet Coke is stepping in to help.

From early November shoppers will be able to purchase one of 140,000 limited edition Diet Coke packs from Asda stores nationwide, and 40p from each purchase will go towards Tickled Pink, helping to fund vital breast cancer research.

The limited edition packs – featuring specially designed Diet Coke cans and a striking outer cardboard case – show Coca-Cola’s statement red ribbon transformed into the iconic pink of the Tickled Pink charity.
