By Laperozy Eric ANTANANARIVO, Sept. 22 (Xinhua) -- The ruling political camp led by Andry Rajoelina would not resume talks with its rivals under pressure, a senior official of the High Transitional Authority said on Tuesday. Norbert Lala Ratsirahonana, former president of the High Constitutional Court (HCC), told a local private radio, Antsiva, that Rajoelina would not return to the negotiation table if anyone of former presidents Marc Ravalomanana, Didier Ratsiraka and Albert Zafy puts pressure on him. As constitutional expert, Ratsirahonana, 71, was appointed by Rajoelina as one of the HTA's 44 members on March 31, and as Rajoelina's special advisor. Another HTA member, general Desire Ramakavelo, also warned Rajoelina against any negotiations if it were arranged by international mediators. The warning came just two weeks before a scheduled African Union meeting on Madagascar, which has got bogged down in a political crisis since December. Mediators from the United Nations, the African Union, the Southern African Development Community and the International Organization of French-speaking Countries have been trying to convince the Madagascan stakeholders to negotiate a peaceful solution to the crisis. In its latest effort to implement the transitional charter and other related agreements, signed early in August in Maputo, Mozambique, the African Union planned to call another meeting here on Oct. 6. The major political camps led by Rajoelina and by his three predecessors, Marc Ravalomanana, Didier Ratsiraka and Albert Zafy, agreed to share power during the 15-month transition at their first face-to-face meeting in Maputo. But the political parties composed of the current transitional authority refused to give up either the presidency or the prime minister as it was agreed by the four politicians in Mozambique, thus bringing the talks to a deadlock. Earlier this month, the transitional authority unilaterally announced what it called a broad-based government, which was rejected by other political forces. Shortly after the announcement of the new government, Zafy, 82, vowed to set up another government to counter the one established by Rajoelina. However, following the news of the scheduled meeting by the African Union, Zafy said he would wait to see the results of the meeting. The current crisis began in December, when former president Ravalomanana ordered the shutdown of the TV and radio station belonging to former Antananarivo mayor Rajoelina. Supported by the armed forces, Rajoelina replaced Ravalomanana as president of the country in March.
