I am not surprised Mr. O'Leary is suing and I would suggest he stands a good chance of winning.
Mr O'Leary is not suing, he is mearly threatening to sue and if he did he has little chance of winning.
Any television programme with either Ryanair or Scientology as its subject is checked and then checked again by their lawyers, as both are notorious for their use of threats of legal action to suppress any negative publicity.
Channel Four would have made sure that the programme was legally, absolutely watertight, prior to transmission.
