Kraft is relaunching Cadbury Dairy Milk Bubbly in a new format designed to melt more quickly.

The bars - which will be available in milk chocolate (rsp: £1.42/90g), white chocolate with a milk coating (rsp: £1.42/100g) and a 90g £1 price-marked pack for indies and c-stores - roll out on 16 January and will replace the current 181g Bubbly bars. The launch will be backed by a £6m marketing campaign.

Kraft has also kicked off a new Cadbury Creme Egg push with a series of ads that show the eggs competing in olympic events.
