(Telecompaper) Isabel dos Santos, the daughter of Angola's president, has launched a takeover bid for Portugal Telecom. In a statement published by Portugal's stock market regulator on 09 November, Terra Peregrin, a Portuguese holding company controlled by Dos Santos, said the offer was for EUR 1.35 a share, a premium of 11 percent on Portugal Telecom's latest share price. The bid, which is conditional on acquiring more than 50 percent of Portugal Telecom's shares, comes a week after Altice launched a EUR 7 billion offer to buy the Portuguese assets of Oi, Portugal Telecom's merger partner. Dos Santos's offer is for the shares of Portugal Telecom SGPS, which owns a 37 percent stake in Oi. The Brazilian operator in turn controls Portugal Telecom's operations in Portugal. Terra Peregrin said it supported a planned merger between Portugal Telecom and Oi, but added that the success of its offer would involve some delays in the merger operation, the Financial Times reports. Dos Santos is also leading shareholder in Nos, PT's main competitor in Portugal. The Terra Peregrin offer does not involve the other shareholders in Nos.
