The Central Energy Italian Gas Holding scandal in 2005 involved Eni and Gazprom. Eni was one of the two companies selected to provide natural gas to Italy. Italian Prime Minister Silvio Berlusconi was a close friend of one of the main owners of Eni. The Italian parliament canceled the contract. In 2009, the European Commission filed formal antitrust charges against Eni. The commission believes that Eni has conspired (planned) to keep competitors from using its gas pipelines. In 2010, Eni proposed to sell its shares of the pipelines TAG, TENP e Transitgas and the European Commission accepted Eni proposal.
