MILAN — The family of former Italian premier Silvio Berlusconi is considering selling a stake of between 20 and 30 percent in AC Milan, the soccer club he bought in 1986 and took to the top of the European game. The club's co-chief executive Barbara Berlusconi, a daughter of the media magnate, told a news conference Wednesday the family was seeking partners and she would travel to the Middle East and later to the United States as part of the process. Rumors have been circulating for some time that the Berlusconis were seeking new investment in a team that is struggling in mid-table in Serie A. Italian soccer has been hit hard by hooliganism and match-fixing scandals and has not seen the kind of heavy foreign investment that clubs in England and France have enjoyed. — Reuters
