WPP announced that Karen Blackett OBE has been appointed as President of its business in the UK. The move recognises the importance of the UK as WPP's home market and its second largest worldwide after the United States, and the ongoing simplification and integration of the company's operations. Karen currently serves as UK CEO of GroupM, WPP's media investment business, alongside her role as UK Country Manager for WPP.

Karen will step down from GroupM to focus full-time on WPP, and her successor as UK CEO of GroupM will be announced in due course.
