Lately, the two leaders have accelerated talks with Prime Minister Oli.
According to JSP sources, Thakur and Mahato discussed power-sharing issues with PM Oli during a series of meetings over the last few days.
Under Article 76(5) of the Constitution, the JSP leaders are expected to join the government.
However, before joining the government, JSP leaders have reiterated that their main demands, including citizenship, the release of its imprisoned cadres, and constitutional amendments, must be met.
According to the source, PM Oli is likely to send the JSP ten ministerial portfolios.
