Efforts at unifying various Maoist groups in Nepal, in a bid to stay politically relevant, have hit roadblocks over differences in ideologies and ambitions of leaders.The biggest political party in parliament in 2008, two years after they gave up arms to end the civil war and join the political mainstream, Maoists were relegated to the third spot five years later.Several splits along the way due to personality clashes of senior leaders have also weakened Maoists, enabling Nepali Congress and Communist Party of Nepal (Unified Marxist Leninist) to overshadow the former rebels.
