French billionaire businessman Bernard Arnault's family and his LVMH luxury goods group will donate €200m to help repair Notre-Dame cathedral in Paris, a statement issued on behalf of Arnault said. 

"The Arnault family and the LVMH group would like to show their solidarity at a this time of national tragedy, and are joining up to help rebuild this extraordinary cathedral, which is a symbol of France, of its heritage and of French unity," the statement said. 

Arnault's pledge follows a similar €100m donation for Notre-Dame from Francois Henri Pinault, who heads the Kering luxury goods company.

President Emmanuel Macron has vowed Notre-Dame will be restored after the massive blaze destroyed the spire and roof of the Gothic architectural masterpiece in Paris.
