There's rich, and then there's Michael O'Leary.
The controversial Ryanair chief executive has become Ireland's latest billionaire and is now the 1,999th richest person on earth, according to Forbes.
O'Leary has an estimated worth of $1.1 billion – which is equal to around €885 million in Ireland or £793 million in the UK.
Most of the 56-year-old's fortune comes from his 3.91% stake in Ryanair, which is worth roughly $905 million.
But as well as his huge holding in the Irish budget airline, high-flying O'Leary owns a large amount of land and horses.
His Cheltenham and Grand National-winning race horses (War of Attrition, Don Cossack, and Rule The World) were key to turning his many millions into a billion.
O'Leary's $1.1bn fortune makes him just over ⅓ as rich as US President Donald Trump – who was ranked 766th this year with a net worth of $3.1bn.
