Michael Islip, the UK chief executive of Digitas, is standing down from his position after 10 years at the agency and will be succeeded by Danielle Bassil.
Bassil, who initially joined as chief operating officer October 2017, takes up the new role immediately having held senior posts at agencies such as JWT, Possible and Grey London and worked on brands including Shell, HSBC and Johnson & Johnson.
Islip was credited with creating the Publicis customer engagement hub 10 years after it was bought by the Groupe. He also led the way with the rebrand which saw LBi dropped form its name.
Sue Frogley, chief executive of Publicis Media UK, said: “I am confident that Dani will prove to be a formidable CEO and I look forward to watching the agency go from strength to strength.
"Dani is a rare talent with a wealth of experience, energy and ideas and I am delighted to welcome her onto my leadership team. With Dani at the helm I know that the Digitas team will go forward into a new era of creativity and growth."
On his departure, Islip said: "The past couple of years has seen some huge changes for the agency but now we're comfortably settled into the Publicis Media family, both in the UK and globally, it's the right time for me to do something else. Digitas is a brilliant agency and it’s been an honour to be part of its story for the past 10 years."
Islip's departure comes three months after chief creative officer Chris Clarke also left the agency, to pursue new opportunities in the tech space. It also follows Publicis Spine's data officer Jason Kodish quitting last week - for the fifth time.
