stayed outside politics until 2003, when he returned to head the opposition. He then unsuccessfully ran for president against Taya in November, campaigning on a moderately Islamist platform, whereas Taya, who had established full diplomatic ties with Israel, was considered pro-Western. Haidallah officially came in second with about 19% of the vote, although he alleged fraud; he was arrested immediately after the election, accused of plotting a coup. Haidallah had also been briefly detained just prior to the vote. On December 28, 2003 he received a five-year suspended sentence and therefore was set free, but barred from politics for five years. An appeals court confirmed this sentence in April 2004. Also in April, his supporters attempted to register a political party, the Party for Democratic Convergence. Haidalla was arrested again on November 3, 2004, accused of involvement in coup plots. The prosecutor sought a five-year prison sentence, but he was acquitted on February 3, 2005 at the end of a mass trial of 195 people. After the 2005 coup Following a military coup against Taya in August 2005, an amnesty in early September freed Haidallah from his sentence, along with more than a hundred others sentenced for political offenses. On December 27, 2006, Haidalla announced that he would be a candidate in the presidential election scheduled for March 11, 2007. He campaigned on a nationalist-Islamist platform, citing the struggle against poverty and slavery as priorities. On February 3, he gained the support of another registered presidential candidate, former opposition politician and prisoner under Ould Taya, Chbih Ould Cheikh Melainine, who dropped out of the race. However, no longer having the political base that came with being the main candidate of the opposition under Ould Taya, Haidallah was even less successful in the 2007 election, coming in tenth place and receiving 1.73% of the vote. After the election, which was won by Sidi Ould Cheikh Abdallahi, Haidalla announced his support for Abdallahi in October 2007. However, following the coup that ousted Abdallahi in August 2008, Haidalla expressed his support for the coup in a statement on August 29, 2008, saying that it was necessary under the circumstances and urging all Mauritanians to support it. He also criticized the negative reactions of Western governments to the coup, alleging that they were interfering in Mauritanian affairs. In July 2007, Sidi Mohamed Uld Haidalla (Mohamed Khouna's son) was detained in Morocco for drug trafficking
