The European Commission (EC) yesterday opened antitrust cases against Telekomunikacja Polska (TP) and Slovak Telecom, the respective incumbent telcos in Poland and Slovakia, on allegations of market abuse. The Financial Times writes that the two former monopolies are accused of hindering competition in their domestic broadband internet access markets, and the formal proceedings follow raids on premises in Poland last September and in Slovakia in January. In the Slovak case, the EC will investigate allegations that the company refused to give alternative operators access to its fixed infrastructure and squeezed profit margins of unbundled local loop (ULL) services. In the Polish dispute, officials will focus on TP’s alleged refusal to give wholesale bitstream DSL access as well as ULL access. The commission stressed that rights of defence would be fully respected and that the opening of proceedings did not imply that it had conclusive proof of infringements.
