Jordan's Islamist opposition has rejected dialogue with the government unless its reform demands are introduced.
The Islamic Action Front says Prime Minister Marouf al-Bakhit is undermining calls for a popular vote to elect the prime minister, who is now appointed by King Abdullah II.
Like much of the Middle East, Jordan has seen opposition protests calling for political change. The demonstrations have not threatened the monarchy but are calling for the king to relinquish some powers.
King Abdullah has urged political parties to meet and agree on reform proposals.
The Islamic Front is Jordan's largest opposition group, associated with the Muslim Brotherhood. Spokesman Zaki Bani Ersheid called Thursday for King Abdullah to personally lead any dialogue.
