West Bengal Chief Minister Mamata Banerjee on Thursday took oath as a member of the state’s assembly.
Banerjee was administered oath by the state’s Governor Jagdeep Dhankhar.
Banerjee, who won the Bhawanipur by-poll by a margin of 58,835 votes, a record for the seat, took the oath in Bengali.
She needed to win the election to retain the chief minister's chair after her defeat at the hands of protege-turned-rival BJP's Suvendu Adhikari in the March-April assembly elections.
Two other newly elected TMC legislators Jakir Hossain and Amirul Islam also took oath soon afterwards.
Jakir Hossain was declared victorious by a huge margin of 92,480 votes from Jangipur, Amirul Islam won from Samserganj by 26,379 votes.
Dhankhar had on Tuesday said he will administer the oath to Banerjee and others, in a departure from the practice of the governor authorising the speaker of the assembly to conduct the exercise. (With PTI inputs)
