Communist Party of Nepal-Unified Marxist-Leninist (CPN-UML) Chairman KP Sharma Oli on September 16 ruled out Madhav Kumar Nepal's return to CPN-UML as he had led a campaign to topple his own party's Government and support the leader of opposition to form a new Government, reports The Himalayan Times. Addressing a training programme organised by the Kathmandu chapter of the CPN-UML in Kathmandu, Oli said Nepal should not be allowed to rejoin the CPN-UML as he set 'his own house on fire'.
