Is Mukul Roy an asset or liability for TMC?

Bharatiya Janata Party (BJP) national vice-president Mukul Roy quit the party to return to the Trinamool Congress (TMC) fold.

Long considered the number-two in the TMC, he fell out with Mamata Banerjee after 2016 as her nephew Abhishek Banerjee started pulling more weight in the decision-making process in the party. Sulking for months, Mukul quit the TMC in 2017 to join the BJP.

But, now since he has returned back to TMC, is Mukul Roy an asset or liability for the party?
