Mars Inc has launched Galaxy Duet – a chocolate bar containing two flavours – in the UK.

The company has developed two lines – Cookies and Cream, as well as Caramel and Shortcake. The bars, to be sold in a single pack format, will be available in August at an RRP of GBP0.60.

Mars described the move as "one of the most exciting pieces of innovation we have ever launched".

Galaxy is the US group's biggest confectionery brand in the UK. It said annual sales were worth around GBP216m.
