Former Italian Prime Minister Silvio Berlusconi said his health is gradually improving, in an interview published on Wednesday. "Doctors have finally allowed me to go back to work a little bit, but without leaving the house," Berlusconi told daily Il Giornale in an interview. The billionaire businessman and four-time prime minister, has been in and out of hospital in past months after contracting coronavirus last September and recently speculation has mounted about a deterioration of his health. Berlusconi, 84, also said the government lead by Mario Draghi and supported by his centre-right Forza Italia party, must press on with tax and justice reforms. "Without (these reforms) the country will not exit the crisis," ha added.
