"We have agreed on a 11 point political agreement and another 25 point deal to clear legal and constitutional hurdles for Regmi's elevation," confirmed senior Congress leader Bimalendra Nidhi.
Regmi who takes over from Prime Minister Baburam Bhattarai has been entrusted the task of conducting parliamentary elections in June. Bhattarai headed a Maoist-Madhesi coalition.
Though the major ruling and opposition parties had agreed on the proposal for Regmi's elevation three weeks ago, the agreement on details was reached after several rounds of meetings.
The parties differed on details regarding ranks to be given to Maoists joining the army, the commission to investigate cases of human rights violations during the civil war and voters list.
Regmi's elevation is being opposed by sections within the major parties and by 23 fringe parties that include the breakaway faction of the ruling Maoist party who have threatened to launch street protests.
