British telecoms provider Vodafone is suing Telecom Italia for abusing its dominant position in Italy, seeking damages of more than 1 billion euros ($1.3 billion).
A Vodafone spokeswoman said in an email on Sunday the civil action in Milan stated that Telecom Italia committed a series of abuses from 2008 to 2013 "with the intention and effect of impeding growth in competition in the Italian fixed-line market".
Telecom Italia rejected the claim saying it was confident it would demonstrate the "total correctness" of its behavior.
