Just Eat, the online delivery platform, has announced that executive chairman and interim chief executive John Hughes is taking a leave of absence to undergo treatment for a medical condition.

Chief financial officer, Paul Harrison, will act as interim chief executive in the meantime while Andrew Griffith, currently senior independent Director, will act as non-executive chairman for this interim period and, with the board, will complete the search for a permanent chief executive.

Hughes will remain a non-executive director of the company.

Harrison joined the group in September last year to replace Mike Wroe, who left after three years with the group.

Chief executive David Buttress announced his departure in February but agreed to serve a minimum one year term as a non-executive.
