Cereal brand Kellogg's is understood to be set to review its international advertising roster as a result of economic conditions.

The review will be a procurement-led process which will look to cut down the number of agencies working on the Kellogg's range. It is likely to involve both UK ad agencies Leo Burnett and Manchester's CheethamBell JWT, which has been behind several recent campaigns for the brand.

A spokesperson for Kellogg’s said: "On an ongoing basis, we have discussions across the broad remit of our partnerships regarding maximizing the effectiveness and efficiency of our operations and efforts. Those ongoing conversations are confidential."
