LONDON — Burson-Marsteller has named Stephen Day as CEO of its UK operations, replacing Amanda Pierce who is leaving the firm.

Pierce became UK CEO of Burson in 2013. Her departure follows the exit of EMEA CEO Jeremy Galbraith earlier this year.

Day has led Burson's UK public affairs practice since April 2014. He took on the additional role of UK chief operating officer at the start of 2016. Under Day’s leadership, the firm’s public affairs team and revenues have seen significant growth.

Before joining Burson-Marsteller, Day spent four years running independent London-based agency Portcullis Public Affairs as MD. In a career spanning 16 years, he has also worked for FleishmanHillard and Weber Shandwick. He started his career in 2000 working for the Conservative Party’s Front Bench Trade and Industry Team.

“As head of our public affairs practice, and later COO, [Day] has led our teams to pursue innovative, creative and data-driven solutions to client challenges,” said Ramiro Prudencio, CEO of Burson-Marsteller EMEA. “This experience will be essential to continuing the transformation of our UK business as we seek to lead in integrated communications spanning all practice and industry areas. Stephen’s background in public affairs and policy will continue to be of particular value to clients as they face a period of change in both the UK and Europe."
