Stuart Wilson, London chief executive of MS&L, said it was a ‘mutual parting of the ways’.
He added that Carr’s departure followed a review of the healthcare practice. ‘There was a sense we needed to address the leadership and direction of the team and how we are working towards the future,’ he said.
Wilson has been in post three months himself after moving from his role as Hill & Knowlton UK corporate comms MD.
Carr’s team has been taken over on an interim basis by Monique da Silva, global head of healthcare for MS&L, who is usually based in the US.
A permanent appointment from outside the company is imminent, said Wilson. ‘MS&L is committed to a strong healthcare practice in London,’ he added. Two years ago the practice had 26 staff; now it is down to 15.
Carr could not be reached for comment. He is believed to have left a month ago.
His appointment was designed to bring stability to the healthcare practice, after key staff had left.
But the high-profile departures continued. Director Jennifer Garratt was poached by Burson-Marsteller (PRWeek, 27 June) and last month director of medical affairs Guy Nasse moved to Huntsworth Health (PRWeek, 29 August).
