"Election of Mansour Hadi happened in a dictatorial and arrogant manner and led to the mocking of the Yemeni nation," Leader of al-Masirah opposition group Mohammad Salim al-Shadadi told FNA on Sunday.
He expressed doubt about Mansour Hadi's ability to materialize the goals of the Yemeni people's revolution, and said, "Mansour Hadi is himself the other face of Ali Abdullah Saleh."
A senior Yemeni opposition leader had earlier said that Mansour Hadi is not able to materialize the goals of Yemen's revolution since he is one of the remnants of the former regime.
"Mansour Hadi cannot materialize the goals of the revolution since he does not recognize the revolution and is part of the former regime which made people start a revolution," Wazah Jalil told FNA on Saturday.
He reiterated that the presidency of Mansour Hadi could merely solve the problem of power transfer in Yemen but other social problems have still remained unsettled.
Earlier, a senior leader of Yemen's revolution had blasted the country's authorities for holding a superficial single-candidate presidential election, and said the Yemeni people demand a full annihilation of Abdollah Saleh's regime and trial of all his allies and affiliates.
"The single-candidate election was a ridiculous political act," Akram al-Shawafi told FNA in February, and underlined that holding a theatrical election has no effect on the determination of the Yemeni people to overthrow Saleh's government.
"We underline that the Yemeni people have not come to the streets to merely topple Ali Abdullah Saleh, but they want the overthrow of the entire regime, its remnants and leaders," he added.
Yemen has witnessed a popular uprising against the regime of Abdullah Saleh since January 2011.
Anti-regime demonstrators hold Saleh responsible for the killing of hundreds of protesters during the uprising. Yemeni people urge that Saleh and his allies should stand trial for their massive crimes and massacre of the people.
Yemen's new president Mansour Hadi took the oath of office before the country's parliament last month. He replaced Saleh, who ruled the country for 33 years before leaving office in a power transfer deal after over a year of political turmoil.
Hadi, who was Saleh's vice-president, was formally inaugurated following a single-candidate presidential election. The election was arranged as part of a US and Persian Gulf Cooperation Council-backed power transfer deal signed in November.
Meantime, people continue protests across the country, saying that they want Saleh and his allies and companions to stand on trial. They also protest that part of the cabinet is still formed of Saleh ministers and affiliates who should be tried instead of being given a post in the cabinet.
