The love-hate relationship between Congress and Trinamool Congress finally ended with Mamata Banerjee walking out of the UPA and Congress pulling out its ministers from the West Bengal government in 2012, which saw the chief minister going through some tough times be it for her controversial remarks, Opposition attacks, rumblings within her own party or the cartoon controversy.
