The Colombian Council of State has lifted the suspension of the sale of the energy giant Isagen. Five senators from different political parties have gone to court to block the sale of the government's majority stake in the company. Isagen has been a profitable venture and has provided an increased amount of revenue to the state budget. Critics charge that the only beneficiaries of the sale of one of the few remaining state-owned companies will be foreign investors. Natalia Margarita reports from Bogota. teleSUR
