BAA told it must sell Stansted
Airports operator BAA has lost its appeal at a tribunal against a ruling that it must sell Stansted Airport, the Competition Commission said.
The defeat marks the latest stage in legal wranglings which have been rumbling on since 2009 when BAA was ordered to sell a number of its airports.
The commission's original ruling found there were problems adversely affecting passengers and airlines at all seven BAA airports, including Gatwick.
But BAA claimed there had been material changes since the commission first made its decision - including its sale of Gatwick.
A BAA spokeswoman said: "We are disappointed by the decision of the Competition Appeal Tribunal, which we will now carefully consider before making any further statements."
Laura Carstensen, chairman of the BAA remedies implementation group and a member of the original inquiry group which reported in 2009, said: "We are very pleased that our decision has been upheld. Whilst BAA is of course entitled to explore the available avenues for challenge, it is now surely time for BAA to accept our findings and proceed with the necessary divestments."
