She said she has spoken to Delhi Chief Minister and AAP leader Arvind Kejriwal and National Conference leader Farooq Abdullah and hinted that some concrete plan could be unfolded shortly.
The Trinamool leader, whose party has 34 members in Lok Sabha, said the next meeting of the opposition parties should take place in some region, rather than in Delhi.
"I have spoken to several leaders including Laluji (RJD leader Lalu Prasad), Arvind (Kejriwal) and also NC leader Farooqji on the demonetisation issue," she said about expanding the opposition group.
The parties whose leaders met here today were Congress, Trinamool Congress, RJD, JD(S), JMM and DMK.
The Trinamool chief, who has been roping in various parties for joint campaign against the Modi government, said, "We may have some differences but we are all against the demonetisation because common people are badly affected due to the demonetisation."
