"After Telangana, the central government will now have to give us Gorkhaland. They cannot deny our old and justified demand. We will intensify our agitation," Giri told PTI.
The GJM leader said Darjeeling hills and its adjoining areas were never part of West Bengal and therefore there was no reason "to forcefully keep us with West Bengal".
"We do not want to remain with West Bengal. It is a mystery how we were attached with West Bengal. We want Gorkhaland," Giri said.
The GJM has threatened that the ongoing three-day strike, which entered the second day today, would be converted into an indefinite one to press for Gorkhaland in case statehood was conferred on Telangana.
BPF Lok Sabha member Bwiswmuthiary said they have called a public rally in Kokrajhar, Assam, on August 5 to renew their demand for separate Bodoland.
"Demand for Bodoland is several decades old. If the Centre can give Telangana, why not Bodoland. We will soon meet Prime Minister Manmohan Singh, UPA chairperson Sonia Gandhi and home minister Sushilkumar Shinde to press our demand," he told PTI.
The UPA on Tuesday unanimously endorsed creation of Telangana state.
