Coca Cola have completely changed and relaunched Diet Coke with new flavours - but there's a catch.

Coca Cola have completely changed Diet Coke, introducing an entirely new range of flavours.

On Wednesday, the company unveiled new cans and packaging, as well as new flavours.  In addition to the classic Diet Coke flavour, there will now be four new additions - Ginger Lime, Feisty Cherry, Zesty Blood Orange, and Twisted Mango.

"We're maintaining the essence of Diet Coke while modernizing the brand to invite a new generation of drinkers to try it," the company said in a post on its website.

Coca Cola say they have been developing the new range for a number of years, whilst insiders say the new range is in direct response to rapidly declining sales.

The bad news is the range will only be available in the US and Canada initially, but if successful, they re likely to be introduced to the rest of the world by the end of the year.

Coca Cola previously changed their Coke Zero range in the UK, with successful results.
