In the midst of nationwide Holi celebrations, Mamata Banerjee - injured earlier this month - held a roadshow in Bengal in high-stakes Nandigram, which votes in the second phase of the state elections. Nandigram will see a high-profile battle between Ms Banerjee and her former aide Suvendu Adhikari, now with the BJP, on Thursday. The Trinamool Congress chief's roadshow comes before campaigning ends in the constituency.
