Coca-Cola agrees to buy Whitbread's Costa Coffee

Coca-Cola is taking on the world of coffee by buying the second largest coffee chain - Britain's Costa - for $5.1 billion.

It's a drive to diversify away from fizzy drinks as countries introduce sugar taxes.

The purchase from British firm Whitbread includes almost 4,000 outlets.

This means Coca-Cola will be taking on some new rivals, Nestle and coffee chain market leader Starbucks - which has almost 29,000 stores.
