Bibi joined the agency six years ago as an account director from the Red Consultancy. She has been responsible for building up the agency's consumer practice and currently leads some of its biggest consumer clients.

The move comes after the agency implemented a new model last year to address the increasing influence of digital and social media in communications. The g4 model is built around four global teams of specialists that work to provide clients with business insights, ideas and engagement between earned, paid, owned and shared media.

Bibi will continue to lead the agency's consumer practice and will be responsible for developing the overall UK business plan, managing its four communities whose leadership team will report to her.

She will report to GolinHarris' president, international Matt Neale.

Matt said: "Bibi is an outstanding leader. Her tenacious new business skills are matched by exceptional client management and her ability to spot and nurture talent. She has pioneered the implementation of g4 ahead of any other team in the world.

"We are so excited to give her the stage she deserves, to help us transition GolinHarris from a great traditional PR agency, to a connected global agency with a bold strategy for the digital world."
