Former Italian prime minister Silvio Berlusconi, a billionaire businessperson who created the country’s largest media company before transforming the political landscape, has died on Monday, according to sources.

Berlusconi, who was 86, had been suffering from leukaemia "for some time" and had recently developed a lung infection.

Berlusconi's Forza Italia party is part of Prime Minister Giorgia Meloni's right-wing coalition, and although he himself did not have a role in government, his death is likely to destabilise Italian politics in the coming months.
