Gangtok, December 8 (PTI): Sikkim Chief Minister Pawan Kumar Chamling’s younger brother R.N. Chamling flayed the Sikkim Democratic Front government’s performance and announced the formation of a new political party on Thursday. R.N. Chamling floated a new party called Sikkim Rajya Manch at a public meeting at Sribadam in West Sikkim and said his outfit will strive to work for change of both the government as well as the system. “The SDF has failed to deliver goods to the people during its 23 years’ uninterrupted rule since 1994,” he said. The younger brother had won Assembly bypolls from Rangang-Yangyan seat, which was vacated by the Chief Minister in 2014 as he had won from two seats. Core agenda “Sikkim and Sikkimese people’s interests will be the core agenda of my party if elected to power,” the 49 year-old MLA said. Chamling junior also came down hard on his elder brother alleging that the Chief Minister was surrounded by chamchas (sycophants) and moneybags. The Chief Minister has “failed” to usher in development in Sikkim, he alleged, and cited unemployment as a major problem in the State.
