Kolkata: More than a month after Mamata Banerjee and her party registered a massive victory in the Assembly polls to return to power in West Bengal for the third straight term, BJP national vice president Mukul Roy on Friday rejoined the Trinamool Congress in the presence of the party chief.
"I am feeling happy that I have been able to come out from BJP. I am feeling happy to meet young people in the party here,' Mukul Roy said.
"Bengal will return to its past glory under the leadership of Mamata Banerjee," he said.
Roy said he left BJP as he could not continue to remain with it.
Mamata Banerjee said: "I feel Mukul Roy feels mentally relieved after leaving BJP. None cannot serve the party."
Banerjee said she never had 'opinion difference' with Roy.
Roy, one of the chief architects behind the TMC's assumption of power in 2011, quit the party in 2017.
He then joined the BJP in the same year.
Apart from Mukul Roy, his son Subhrangshu, a BJP leader, aso joined the TMC.
