Britain's Competition Commission has said airport operator BAA's dominance will come under scrutiny as part of a wide-ranging examination of the UK airports market.
Spanish firm Ferrovial, which led a consortium that bought BAA for £10.1 billion last year, has faced criticism for overcrowding, long security queues and technical glitches in baggage handling equipment at Heathrow, Europe's busiest airport.
'At this stage, we have no preconceived ideas of what our conclusions might be; and if we were to identify competition problems, what the appropriate remedies might be,' the Commission said in a statement.
There has been media speculation that Ferrovial may be forced to sell one or more of its three London airports, Heathrow, Gatwick and Stansted.
The Commission said it aimed to publish its 'emerging thinking' in early 2008 and its provisional findings around this time next year.
