Global Infrastructure Partners, a $51bn fund manager behind Edinburgh Airport and the Port of Melbourne, has sold part of its stake in Gatwick Airport at a price that suggests it has more or less doubled its money since 2009.

GIP and its consortium partners, which include Abu Dhabi’s sovereign wealth fund and California’s state pension fund, have sold a 50.01% interest in Gatwick to the French operator Vinci Airports for £2.9bn, it announced on December 27.
