In a memorandum to Minister for Development of North Eastern Region (DoNER) Jitendra Singh, the delegation said the reservation for Limboo/ Tamang may be considered out of 17 unreserved Assembly seats.
The team also demanded that the strength of the state legislature be increased to 40 from present 32, an official release said.
In their meeting with the Minister, the team suggested that in the event of any new community being declared as Scheduled Tribe in future, they may be accommodated within the proposed overall increased size of 40.
The Minister appreciated the self-discipline and hard work with which the people of Sikkim have achieved exemplary literacy and growth rate.
Referring to Prime Minister Narendra Modi's recent visit to Sikkim, Singh said this only authenticated the high priority that the Prime Minister attaches to the state.
He also lauded Sikkim's progress as the most developed state of the country in the field of organic farming and said the union budget has allocated exclusive funds for organic farming which in years to come may become a very important option for young entrepreneurs and start-ups.
