Political intrigue is a recurring theme of Nepal. Since the Nepalese royal massacre of 2001, the country broke out into civil war that only ended in 2006, the victors being UCPN-M power brokers who forced Parliament and King Gyanendra to integrate them; the king later was forced to resign. The two main leaders of UCPN-M are ex-Prime Minister Baburam Bhattarai and party head Prachanda. Despite their once powerful posts and many disgruntled members having left the party with a few cadres after disputes and failures to get economic and political traction, the party never suffered from fallout as great as it has in 2015, when Baburam Bhattarai on 26 September severed ties with Prachanda and the UCPN-M amidst the Constitutional crisis and early days of the blockade, reducing the once formidable UCPN-M to an also-run political force despite its &lt;a href="2013%20Nepalese%20Constituent%20Assembly%20election"&gt;80/600&lt;/a&gt; parliamentary representation. Bhattarai stated "chances of me joining an old or a cracked house is out of option". The ruling Nepali Congress itself had been under intense pressure due to failure to act on quake relief and the blockade, this and the UCPN-M split paved the way for Khadga Prashad Oli of CPN-UML to become PM on 11 October.
