Pharol, formerly Portugal Telecom SGPS, has lodged court proceedings against three former PT directors, but this is just the start as the former Chief Executive Zeinal Bava and accountancy firm Deloitte are next on the list.
The lawsuit lodged on Thursday cites Henrique Granadeiro, a former chief executive of PT, Pacheco de Melo, PT's former finance director and Amílcar Morais Pires, the former PT director representing major shareholder Banco Espírito Santo.
Notice of the cases against the three former directors was received by the stock market regulator CMVM and released to the press on Friday.
