Mr. Aristide spoke for 20 minutes, mostly in Creole. He did not comment directly on the candidates in the presidential runoff on Sunday, but he criticized the electoral process, denouncing the exclusion of political parties, including his own, Fanmi Lavalas, which officials barred from the first round of voting last year on what was described as paperwork problems.

The Secretary General predicted that the two presidential candidates Michael Martelly and Mirlande Manigat in the second round will not have enough of Deputies and Senators to have a majority in both houses evoking the problem of the cohabitation with the majority. “The President must choose a prime minister which must be voted and accepted by the houses… We hope that this period will be resolved quickly” stressing that “this is a difficult phase in a democracy, when a president and the houses must get along on a Prime Minister and a government.”Standing at a lectern in the shade of a veranda steps away from the private jet that carried him home,

Mr. Aristide helped lead a popular revolt that ended the Duvalier family’s nearly 30-year dictatorship. He became president in Haiti’s first democratic elections in 1990, was soon ousted in a coup in 1991 but then returned to power in 1994 after the United States military forced out the military regime.

Mr. Aristide was re-elected in 2000 in an election boycotted by the major opposition parties, and while he inspired great loyalty among the poor he was criticized by many for corruption, an autocratic style of leadership and the violent suppression of political opponents.

Amid an armed uprising, led in part by former members of the Haitian Army that Mr. Aristide had disbanded, he left Haiti on Feb. 29, 2004. He has said American diplomats kidnapped him, but the United States has long denied the accusation.With Haitian elections tense, fragile affairs in normal times, it remained unclear what effect Mr. Aristide, a polarizing figure beloved by the poor but dismissed by others as corrupt and autocratic, might yield on the country. He has said he is coming back just to work on his educational foundation, but Western diplomats working to keep him out of the country were skeptical given the timing of his return.
