Ryanair's appeal against a British competition ruling, which ordered it to sell most of its shares in Aer Lingus, has been rejected.
Britain's Competition Commission – now the Competition & Markets Authority - had previously ordered the airline to reduce its 29% stake in Aer Lingus to no more than 5%.
Ryanair appealed the decision to the country's Court of Appeal, but this has today been rejected.
The airline said it noted the court's decision and said it would now take its case to the British Supreme Court on human rights grounds.
"Ryanair will now appeal this case... as it raises human rights issues of significant public importance, including the scope of protection offered to businesses by the right to property."
The airline has also sought the withdrawal of the order to sell much of its Aer Lingus stake in light of IAG's recent offer to buy the airline.
Ryanair said the IAG bid "wholly disprove[s] the CMA's unsubstantiated claim that Ryanair's shareholding somehow prevented other airlines from merging with or bidding for Aer Lingus.
"Clearly the CMA's case has now been totally undermined by the IAG offers."
Aer Lingus has welcomed the court's decision.
