The Janata Samajwadi Party (JSP), led by Ashok Rai, has split.
Co-chair Renu Yadav and other leaders have returned to the Janata Samajwadi Party Nepal, led by Upendra Yadav.
JSP Nepal Chairman Upendra Yadav and JSP Co-chair Renu Yadav have signed an agreement on party unity.
However, JSP Chairman Rai said that he did not join the merger.
"Renu Yadav, Pradip Yadav, and some other colleagues have returned to the JSP Nepal. I am not involved in this unity," he said.
This development follows a party unity agreement reached on Sunday between the JSP Nepal and the Loktantrik Samajwadi Party (LSP) Nepal, led by Mahantha Thakur.
