A gram panchayat, which consists of a group of villages, is administered by a village council headed by a "Pradhan". As per the West Bengal Panchayat Act, 1973, each Block has a "Panchayat Samiti", whose members include the "Pradhan"s of the constituent gram panchayats, and the MLAs from the block. A "Panchayat Samiti" is headed by a "Sabhadhipati". The third tier of the Panchayati Raj is "Zilla Parishad", a district level organisation with the "Sabhapati"s of the constituent "Panchayat Samiti"s and the MLAs from the district as its members. A "Zilla Parishad" is headed by a "Sabhadhipati". For the Darjeeling district, the "Zilla Parishad" has ceased to exist, but a similar organisation for the Siliguri subdivision exists, which is designated as a "Mahakuma Parishad".
