Many trains crisscrossed the Ganga—and the Hooghly—since Rashtriya Janata Dal president Lalu Prasad Yadav and Trinamool Congress chief Mamata Banerjee crossed swords over the performance of the railways. That was then, when the two were railway ministers in the ten-year UPA rule, each taking turns to head the national transporter. Mamata dogpiled on Lalu since assuming charge in 2009 and belittled her predecessor’s claims of a phenomenal turnaround in the cash-strapped railways on his watch as political whataboutery. Lalu disliked her and the feeling was mutual. Cut to 2021, the ailing Bihari patriarch, serving a long sentence for a fodder scam, is firmly behind his once bete noire as she battles a snapping-at-the-heels BJP in the West Bengal assembly elections staggered over eight phases this March-April. Forged on old anvils, they have a common axe to grind—much like my enemy’s enemy is my friend.
