1Another MLA quits Trinamool Congress
On Friday afternoon, TMC leader Kabirul Islam resigned from the post of general secretary of the party's minority cell.
Earlier in the day, TMC MLA Silbhadra Datta had resigned from the party.
TMC MLA Jitendra Tiwari resigns as Asansol Municipal Corporation chief, days after accusing the West Bengal govt of depriving the industrial city of central funds. He has also resigned as the TMC president of Paschim Bardhaman district.
On Wednesday, TMC leader Suvendu Adhikari submitted his resignation as an MLA. He was the MLA of Nandigram constituency in Purba Medinipur district. He had resigned from the state cabinet last month.
2Speaker rejects Adhikari's resignation
West Bengal assembly speaker Biman Banerjee refused to accept Suvendu Adhikari's resignation.
"I have examined the letter and found that the date is not specified in it. I had not been informed that his (Suvendu Adhikari) resignation is voluntary and genuine. So it is not possible to accept it. I have asked him to appear before me on 21 December," said Banerjee. Adhikari had resigned on Thursday.
Banerjee added that he has not accepted Adhikari's resignation as it does not conform to the provisions of the Constitution and the rules of the House.
3Z category security for Adhikari
The ministry of home affairs provided 'Z' category security cover to former West Bengal minister Suvendu Adhikari.
Adhikari has been provided with the heightened category of security while he is based in West Bengal. The CRPF will man him with bullet-proof vehicles. However, when he is out of West Bengal, he will be provided Y-plus security cover by the CRPF
