Mark Inskip (pictured) had been at Kantar for six-and-a-half years and had held the role of managing director of media for the UK and Ireland since February 2019.

Louise Ainsworth, managing director, Europe, Middle East and Africa, will oversee Kantar’s UK and Ireland media work on an interim basis while a replacement for Inskip is sought.

A spokesperson for Kantar said: “Mark Inskip left his position as managing director media UK&I to pursue a new opportunity outside of Kantar. Mark leaves with our best wishes.

“With the support of a strong leadership and dedicated team of research professionals, we are focused on delivering for our clients.”
