Mike McTighe has been appointed the first chairman of Openreach, BT's local fixed network business.
McTighe, who takes up his role from January, is an experienced telecoms executive and regulator who spent eight years on the board of Ofcom.
He will oversee the new Openreach Board - which will operate from early 2017 - and be instrumental in selecting further independent members to join that Board.
BT announced in July 2016 it would implement governance changes to make Openreach more independent and transparent. Central to these was the creation of an Openreach Board with an independent chairman and a majority of independent members.
This Board will be accountable for setting the strategy and overseeing and managing the performance of Openreach, working with CEO Clive Selley and his management team. It will ensure that Openreach treats all customers equally whilst investing in better service, broader coverage and faster speed broadband.
BT Chairman Sir Michael Rake said: "I am delighted that Mike has agreed to be the first Chairman of Openreach. He has extensive experience and I am sure Openreach will benefit from his detailed industry and regulatory knowledge.
"We promised in July to create an Openreach Board and we are delivering on that promise. I remain hopeful this significant move by BT can help to underpin a sustainable, proportionate and fair regulatory settlement that is in the interests of the whole country."
