The move comes as BT enters the final months of a regulatory review with Ofcom, which is expected to complete in the summer, following which Prescott will depart.
Prescott was managing director of corporate comms and public affairs at Weber Shandwick for almost nine years before his current job and was The Sunday Times’ political editor for a decade before that.
His successor will need to set the direction of travel for the company’s comms in the light of Ofcom's conclusions. Its initial conclusions, published in February
, were that the company should provide better quality of service, reform Openreach and open up its network to competitors.
A BT spokesperson said: "We have commenced a search process to find a successor for our group director of corporate affairs, Michael Prescott. No formal decision has been taken on a replacement or around the potential timing of any change.
"After seven years with the company, Michael feels the time is now right to start the process to hand over to someone who can take BT on to the next stage of its journey. In the meantime he is continuing in his role, and we will continue to rely on his clear-headed advice and professionalism."PRWeek also reported yesterday that Prescott's counterpart at broadcaster Sky would leave his role shortly.
