TMC MP Santanu Sen has given Zero hour Notice in Rajya Sabha over the name change of West Bengal to 'Bengal.'
Last July, the West Bengal Assembly had unanimously passed a resolution to change the state's name.
In July this year, the Centre had refused Banerjee's demand saying that a constitutional amendment is needed to change the name of a state.
On September 18, West Bengal Chief Minister Mamata Banerjee had met Prime Minister Narendra Modi in Delhi and raised the issue related to the proposal of renaming the state.
