Chief Minister Mamata Banerjee on the occasion thanked the people for giving an overwhelming mandate to serve them and expressed happiness by saying that "history repeats itself".
"On the momentous occasion of completion of three years in office, we express our deep gratitude to 'Maa, Maati, Manush' of Bengal for giving us their overwhelming mandate to serve them," the West Bengal chief minister said in her message on a social networking website.
Noting that "history repeats itself," Banerjee said, "Once again, the people of Bengal have reposed their trust and confidence on us through their huge mandate in the recently-concluded Lok Sabha election."
"We bow our heads down with gratefulness," she said referring to the people of the state.
The Trinamool Congress had won 185 seats in 2011 elections for the 294-member West Bengal Assembly and has added a few more to its kitty in by-elections held thereafter.
The party has won 34 Lok Sabha seats out of 42 in West Bengal in 2014 Lok Sabha polls.
To mark the occasion, the Government of West Bengal would today confer the state's highest civilian awards "Bangabibhusan" and "Bangabhusan" to 33 individuals for outstanding contribution in respective fields at a glittering function at the Science City Auditorium.
