Kellogg's has signed up footballer Ian Wright, Channel 4's 'Supernanny' Jo Frost and TV presenter Philippa Forrester to back its biggest multi-brand on-pack campaign to date.

The celebrities are supporting Kellogg's Wake Up To Breakfast campaign, which aims to increase sales and consumption of cereals by highlighting the importance of breakfast as a fuel for mental ability and physical activity.

From this month they will appear on 100 million packs of Kellogg's cereals alongside a series of breakfast facts, such as 'children who eat breakfast tend to do better at school'.

TV advertising fronted by Ian Wright and point-of-sale materials featuring all three celebrities will also begin from this month.

In addition, Kellogg's will dedicate more on-pack space to the campaign during National Breakfast week which runs from 27 August.
