The former BT Group chief Philip Jansen is being lined up as the next chairman of Heathrow Airport as Britain's biggest aviation hub prepares to deliver an expansion costing close to £50bn.
Sky News has learnt that Mr Jansen, who chairs the FTSE-100 marketing services group WPP, is in advanced talks with Heathrow's board and shareholders about taking on the role.
If the discussions reach a successful conclusion, sources said an announcement could come within weeks.
Mr Jansen is said to have emerged as the frontrunner from a shortlist of candidates compiled by headhunters at Russell Reynolds Associates.
His experience as the boss of BT, a regulated utility, is said to have been key to his selection as the preferred candidate.
Mr Jansen has also run companies including MyTravel and Worldpay.
The appointment of a successor to Lord Deighton, who has held the post for nine years, comes at a critical time for Heathrow.
In August, the airport submitted a revised expansion plan consisting of a third runway costing £21bn, £12bn for a new terminal and stand capacity, and £15bn to modernise the current airport through the expansion of Terminal 2.
The existing Terminal 3 would ultimately be closed.

Heathrow handled a record 83.9 million passengers and is adamant that a third runway is essential to the growth of Britain's economy, given the volume of exports which pass through the site.
"It has never been more important or urgent to expand Heathrow," the airport's chief executive, Thomas Woldbye, said in August.
"We are effectively operating at capacity to the detriment of trade and connectivity.
"With a green light from Government and the correct policy support underpinned by a fit for purpose regulatory model, we are ready to mobilise and start investing this year in our supply chain across the country.
"We are uniquely placed to do this for the country; it is time to clear the way for take-off."

The expansion remains opposed by many airlines alarmed by the prospective increase in charges to use the airport, as well
It has, however, been backed by the government, with Rachel Reeves, the chancellor, saying that a third runway "ould unlock further growth, boost investment, increase exports, and make the UK more open and more connected as part of our Plan for Change".
Heathrow's next chairman will lead a board dominated by representatives of the airport's principal shareholders.
Mr Woldbye apologised in May for being asleep during the power outage in March which forced Heathrow's temporary closure.
The airport said it would implement the recommendations of a review conducted by former transport secretary Ruth Kelly.
Heathrow's search for a new chairman comes months after the most significant changes to its ownership structure in years.
Ardian, a French investment group, now owns 32.6% of the company following a series of transactions over the last 12 months.
Saudi Arabia's Public Investment Fund has also become an investor.
Heathrow has never formally announced Lord Deighton's intention to step down, other than a disclosure in its annual report in which he wrote:
"In light of the recent changes to the HAHL [Heathrow Airport Holdings Limited] board…the nominations committee…has asked me to extend my appointment for a limited period to help ensure a smooth transition whilst new non-executive shareholder directors become familiar with the business and a new chair is appointed.
"I have therefore agreed to extend my role as chair for a limited period to ensure continuity and stability on the HAHL Board during this period of transition."
A Heathrow spokesperson declined to comment, while Mr Jansen could not be reached for comment.
