A crisis hitting Telecom Italia is having political repercussions for the Italian prime minister. An advisor to Romano Prodi, Angelo Rovati, has resigned over a row about a strategy shift at the telecoms giant. He made the announcement while on a visit to China with Prodi. Rovati said advice he had given about future strategy had been ‘‘deliberately misinterpreted’ and that he was standing down to avoid damaging the government. Speaking after the resignation Prodi said the affair would be discussed in parliament after his return to Italy.
