Two Members of Parliament from Sikkim, PD Rai and Hishey Lachungpa, on Tuesday, called on Union Home Minister Rajnath Singh at his North Block Office in New Delhi.

The two leaders presented Mr Singh a memorandum, seeking his intervention in resolving the protracted Limboo-Tamang seat reservation issue in the Himalayan state.

In the memorandum, the MPS have requested that amendments be made to the Constitution by the Parliament to make changes in the number of seats in the Sikkim Legislative Assembly.

They also enclosed a copy of the letter written to him by chief minister Pawan Chamling in February 2018, elaborating in detail the issues under consideration.

“He (Mr Singh) has assured to look into the matter expeditiously,” the MPs said, according to a government release issued here on Tuesday.

In 2003, the Limboo and Tamang communities were granted tribal status by the then NDA government. After that, they started demanding seat reservation in the Assembly, as Scheduled Tribe communities. The state government has favoured the Burman Commission’s 40-seat formula and has placed the same at the Centre for resolving the seat issue.

A decision is, however, pending at the Centre. However, certain political outreach and organisations here are demanding seats from within the existing 32 Assembly seats. Meanwhile, the MPS also thanked the home minister for the security clearance given to Karmapa Ogyen Trinley Dorjee to visit Sikkim.

“This was an issue taken up at the highest level by the Hon Chief Minister of Sikkim,” the release said. They also requested Mr Singh to expedite the process of granting tribal status to 11 communities who had been left out from the scheduled tribe list.
