He slammed the BJP-led NDA government at the Centre for "never being serious" about finding a permanent solution to the statehood issue of the Gorkhas.
Accusing the BJP of never clarifying its position on the Gorkhaland issue, Bimal Gurung demanded the resignation of Darjeeling MP Raju Bista.
Gurung, who was going to Siliguri by train, left it and went there by road as an Adivasi organisation put up a rail blockade to press for their demands.
Those 17 councillors of the Darjeeling Municipality joined the BJP in New Delhi in June last year, giving the saffron party a majority in the 32-member board.
Banerjee, along with Chief Secretary Alapan Bandopadhyay and state ministers Aroop Biswas and Firhad Hakim, held an hour-long closed-door meeting with Tamang.
Tamang, before boarding a flight to Kolkata, told reporters in Siliguri that Gurung was a fugitive and any association with him was improbable.
The purpose of his visit to north Bengal is to assess the "ground realities", Dhankhar said, adding that he has received reports about the prevailing situation in the area.
Tamang, along with Gorkha Territorial Administration chairman Anit Thapa, are scheduled to meet Banerjee at the secretariat to discuss matters of concern, the sources said.
Gurung had made a dramatic reappearance in Kolkata on October 21, quit the BJP-led NDA and aligned with TMC.
Gurung’s support to Mamata is believed be a relief for the ruling Trinamool Congress as the party failed to bag a single seat out of eight in the region in 2019.
According to a TMC leader, the party was in talks with the Binay Tamang (faction) of the GJM to ensure that it gets along with Gurung's organization, ahead of the 2021 elections.
Accusing the BJP of not keeping its commitment on the Gorkhaland issue, Gurung said his party would support the TMC in full swing in the 2021 Assembly elections
The Centre did not discuss the issue with us before convening the meeting, said Mamata Banerjee government.

Gurung claimed that Binay Tamang had taken crucial decisions without consulting him or the GJM central committee.
The state had accused its northern neighbour of giving shelter to the GJM supremo who is wanted in several cases including Unlawful Activities (Prevention) Act) (UAPA), murder, rioting and arson.
