French MP and billionaire Olivier Dassault died in a helicopter crash in north-western France.

Iran Press/Europe: French billionaire Olivier Dassault, a politician and scion of the Dassault aircraft-making family, was killed in a helicopter crash on Sunday.

According to French media, Dassault, 69 and a father-of-three, died around 6 pm (1700 GMT) when his helicopter crashed near the upmarket coastal resort of Deauville in northwest France, parliamentary and investigation sources told AFP.

French President Emmanuel Macron led tributes, saying in a tweet that "Olivier Dassault loved France. Captain of industry, local MP, reserve commander in the air force; throughout his life he never stopped serving our country".

The Dassault Aviation group has been a leading French plane manufacturer for the last 70 years and is behind the Falcon private jet, the Mirage warplane, and most recently the state-of-the-art Rafale fighter jet fighter. 219
