Stansted’s owner BAA, which recently renamed itself Heathrow, is being forced to sell the airport by competition authorities, after losing its final appeal in August.
Suitors so far include Manchester Airports Group, New Zealand-based investment manager Morrison & Co, Australia’s Macquarie and buyout stalwart TPG.
Stansted is thought to be worth upwards of £1bn.
But the Sunday Telegraph has reported that Malaysia Airport Holdings (MAH) has made a late approach for the London airport, an intervention that Heathrow hopes could push up the asking price.
A spokesperson for Heathrow declined to comment, while MAH did not respond to a request for comment yesterday.
ING and Deutsche Bank are handling the sale for Heathrow.
