Ryanair boss Michael O’Leary has slammed pensioners who voted for Brexit as he suggests it will be "a good thing" when they "die".

The CEO now faces backlash from critics who have branded him "abhorrent" following the comments.

O’Leary described Brexit as "the greatest act of economic self-harm perpetrated by any western government".

He added that leaving the single market was the "dumbest f***ing idea in history delivered by the dumbest politicians in history," before he attacked former Prime Minister Boris Johnson and GB News presenter Nigel Farage, calling them "lunatic halfwits."

Speaking to The Times, the Irish businessman said that when over-70s who voted for Brexit "die out in the next 10 or 15 years — which is a good thing — the younger people will change things.

"I’m not sure the UK will ever rejoin the EU but it will, in my view, rejoin the European single market in the next five to ten years, in a Swiss-style deal or a Norwegian-style deal."

His "extraordinary" remarks have been met with fury as he is condemned for his lack of "understanding" of Brexit.

Writing online, one social media user said: "Michael O'leary, leaving the institution of Europe wasn't just voted for by the over 70s, as for wishing them dead you are an abhorrent so called human being.

"Sour grapes is a bad emotion to harbour."

Speaking on GB News, Kwasi Kwarteng added: "I find that pretty extraordinary.

"He doesn't understand, he's a businessman. He doesn't really understand about democracy or care about sovereignty or any of the issues really in Brexit."
