Jordan's Islamist opposition on Wednesday urged constitutional amendments to curb the king's power in naming heads of government, arguing the premiership should go to the leader of the majority in parliament.
"We want constitutional amendments that would limit the king's power in appointing whoever he wants to head a government without any constitutional restriction," said Zaki Bani Rsheid, the head of the powerful Islamic Action Front (IAF).
"The leader of the majority in parliament should become prime minister, or get elected directly by the people," he told AFP.
Under the constitution, the king names and dismisses prime ministers.
Bani Rsheid said the IAF, the political arm of Jordan's Muslim Brotherhood, had "prepared a thorough study of the required amendments in the constitution," which was adopted in 1952.
The IAF on Tuesday demanded the dissolution of parliament and removal of Prime Minister Samir Rifai's government on allegations of "fraud" in Jordan's November election.
"The elections were marred by fraud. We have evidence of the use of tens of thousands of fake identity cards during the electoral process," said IAF secretary general Hamzeh Mansur.
Bani Rsheid said the IAF wanted a "transitional government which should hold new, free and transparent elections on the basis of a law that is just and democratic."
The IAF boycotted the November vote in protest of the electoral law's under-representation of urban areas where Islamists are strong.
Bani Rsheid said the Islamists planned to organise a nationwide demonstration alongside leftist parties and trade unions to call for "political reforms as well as limiting hikes in commodity prices."
