LONDON — U.K. communications minister Stephen Carter — one of the frontrunners in the race to be the next chief exec of commercial broadcaster ITV — is to step down from his government post in July.

Carter is due to deliver a blueprint for the future of the U.K. media and telecoms sectors Tuesday, in the form of a detailed report, Digital Britain.

He is one of those thought to be a candidate to take the top post at ITV when Michael Grade switches to the role of non-executive chairman by the end of the year.

Carter has had a high-flying career, having occupied a series of leading positions in the media. These have included chief exec at leading PR firm Brunswick, chief exec at media regulator Ofcom, managing director at cable company NTL, now known as Virgin Media, and head of the U.K. and Ireland office of ad agency J. Walter Thompson.
