Bell (pictured) leaves the agency after less than a year in the role.  

Formerly chief strategy officer at M&C Saatchi, Bell joined Hall & Partners in March 2018 to help the company in its aims to transform into a strategic brand consultancy.

Hall & Partners confirmed the two had parted company “by mutual consent”.

The company is not seeking to replace Bell. Managing partner Branka Orosnjak will take over sole responsibility for running the consumer team. 

Orosnjak joined Hall & Partners in 2014, initially holding the position of senior partner, head of client relations and marketing, and later becoming managing partner.

Vanella Jackson, global chief executive at Hall & Partners, said: “I have full confidence in Branka as an outstanding leader. She has demonstrated tenacity, vision and an ability to inspire. I am excited about what Hall & Partners will do under her brilliant leadership.”
