My friends already backing the fixed odds for more then 2 years..
https://www.betfair.it/Below here you find the reason:
Pursuant to the Decree of the State Monopolies Autonomous Administration (AAMS) on January 2, 2007, governing the removal of cases offered in the absence of authorization, through computer network, games, lotteries, betting or pools winnings with cash, with which art has been implemented. 1, paragraph 50, of Law December 27, 2006, No. 296, the requested site is not accessible because it lacks the necessary permissions to operate the collection of games in Italy.
The list of authorized operators to electronic game is available on the corporate website
http://www.aams.gov.it.
P.S. Betfair has the rights to regulate the exchange within the Italian territory but, chose not to see, not to hear and not to bring the betting exchange within the Italian territory. Despite Italian bureaucracy tends to kill foreign investment, there is always the European community that has allowed the regularity of online gambling with the latest release of the green paper which regulates the gambling within the european territory. If Betfair decided to legalize their activity within some European countrys (France, Italy, etc etc) the Liquidity available in the sport market exchange will probably increase up to 200% or more.
Do not take this news as truth certain. There are informations that hard to find even on the web so it is difficult to define with certainty the true reason why Betfair can not legalize their activities in some European countries or if they really choose not use their rights to regulate betfair exchange.
