O'Leary, 62, was in the Belgian capital to speak at a press conference and deliver a petition to protect overflights in Europe amid the news Ryanair pilots based in Belgium had called a strike. He was delivering an interview - alongside a cardboard cut-out of European Commission chief Ursula von der Leyen, one black-clad woman ran up and smushed the pie into his face. O'Leary reeled away and ducked his head down to avoid a potential blow - giving a second woman the opportunity to run up behind him and deliver a second spatter of cream down the back of his neck. 'Welcome to Belgium!', the activists cheered as they ran off, before O'Leary sportingly replied, 'well done'.
