The Milan Stock Exchange board of directors on Friday June 22, 2007 approved a proposal from London Stock Exchange for a collaboration, a person close to the discussions said. The person would not elaborate on the nature of the collaboration, but the Italian news agency APcom reported that the proposal values the Italian exchange at 1.6 billion (US$2.15 billion) and would involve creating a holding that would control both exchanges managed by 12 advisers, seven British and five Italian.
