MILAN, April 6 (Reuters) - Four-times Italian prime
minister Silvio Berlusconi has been diagnosed with leukaemia, a
source close to the matter said on Thursday.
The source confirmed a report by the Corriere della Sera
daily.
The 86-year-old Berlusconi has been treated in intensive
care since Wednesday in a cardiac unit of Milan's San Raffaele
hospital, after suffering breathing problems.
The billionaire media tycoon, who made his fortune from
commercial television, has suffered repeated bouts of ill-health
in recent years and had came out of the same hospital just last
week.
