72andSunny, Starbucks’ global ad agency, is not affected by the review. The brand wants to use a specialist shop to handle creative across its European markets in particular. 

Starbucks has sent a request for information to several agencies in the UK ahead of a review overseen by Creativebrief.

The coffee chain also works with Oliver, which provides an in-house unit that manages in-store and point-of-sale activity.

Howard Schultz stepped down as Starbucks’ chief executive in April and was replaced by chief operating officer Kevin Johnson. 

A Starbucks spokeswoman confirmed the review and added: "With 41 countries in EMEA, we want to celebrate how Starbucks’ coffee leadership comes to life across a diverse region."
