West Bengal governor M K Narayanan resigned on Monday capping speculation for the past few days on whether he would step down following the centre's hint in the second week of June that the new dispensation wants several governors to step down.
According to sources the governor sent his resignation to the President on Monday.
Sources also said a farewell function may be organised inside the Raj Bhavan shortly. The governor has also reportedly packed his bags.
"The governor will be here till July 4. There will be a small reshuffle in the cabinet on July 2 and I want him to sign it. It is a Constitutional post and I don't want to comment on it," said chief minister Mamata Banerjee in the assembly on Monday.
His tenure was supposed to end on January 15, 2015.
M K Narayanan, 80, took over as the governor of West Bengal in 2010 a year before the Trinamool Congress came to power. A former IPS officer of the 1955 batch Narayanan went on to become the IB director from 1987 to 1992.
In 2004, he was appointed by the UPA Government as the security advisor to the prime minister of India.
Last week, Narayanan was questioned by CBI officers for connections with the Augusta Westland helicopter deal.
A number of governors including B L Joshi (Uttar Pradesh), H R Bhardwaj (Karnataka), J B Patnaik (Assam), Ashwini Kumar (Nagaland) and Shekhar Dutta (Chhattisgarh) have already submitted their resignations.
"I have not resigned yet. I am not obliged to tell you what I will do. Once I take a decision I will let you know," Narayanan said on June 16 on the sidelines of a programme.
In the debate over the past few days, Trinamool Congress targeted BJP over the issue with chief minister Mamata Banerjee siding with the governor, with whom she shared a good relation.
"The governor is not a political person. It will be sad if he is removed on political grounds," Subrata Mukherjee, senior Trinamool Congress leader and state panchayat minister has remarked.

Mamata Banerjee too met Narayanan at the middle of the month. In her close circles, she remarked that she is opposed to the manner in which Narayanan is being nudged to resign.
Soon after coming to power, the NDA government mulled the removal of some of the governors who were reportedly close to the UPA government and the Gandhi family.
In the first three years of the Mamata Banerjee government, Narayanan was flooded with complaints in a host of issues ranging from human rights violations to Saradha scam, tiff between the State Election Commission and the state government over 2013 panchayat polls and School Service Exam related irregularities.
