Heathrow is facing further turbulence after investors accounting for 35% of the airport said they are selling up.
Their decision to quit follows Ferrovial’s sale of its 25% stake for £2.37bn to French firm Ardian Capita and PIF at the end of last year.
Now three other shareholders have opted to exercise their “tag-along” rights. It is believed those shareholders are Canadian investor Caisse de dépôt et placement du Québec, Singaporean sovereign wealth fund GIC, and the Brisbane-based Australian Retirement Trust.
