The Chief Executive of Ryanair has launched a scathing attack on the Commissioner for Aviation Regulation Cathal Guiomard.
Michael O'Leary made the comments as he announced his airline is to take a judicial review of a decision to increase charges for check-in desks at Dublin Aiport.
Mr O'Leary claims that charges for check-in desks at Dublin Airport have increased by 200% in the past five years.
The increased charges were approved by the Aviation Regulator. O'Leary says this shows that the regulator is failing in his statutory duties.
Ryanair has previously taken seven court actions against the regulator and lost six.
Mr O'Leary described regulator Cathal Guiomard as an overpaid, underworked poodle, intent on rubber stamping double charging at Dublin Aiport.
Commenting on the succession of Brian Cowen as Taoiseach, Mr O'Leary said anyone could do a better job than the outgoing Taoiseach. He said Bertie Ahern had been a disaster for the Irish economy.
Asked when he would leave the post of Ryanair Chief Executive, he said breaking up the monopoly of Dublin Airport was one of his key priorities, adding passengers do not care whether he stays or goes, but he confirmed he intends to go in two or three years.
