Trinamool Congress MP Derek O'Brien lambasted Prime Minister Narendra Modi and Union Home Minister Amit Shah on Saturday following Gujarat Chief Minister Vijay Rupani's 'surprise' resignation. <br /> <br />Taking to Twitter, Derek O'Brien said, "Is anyone counting? 'The Two' really think CM stands for Chairs Musical." <br /> <br />Vijay Rupani resigned as Gujarat Chief Minister on Saturday, a year before the state Assembly elections. Rupani said he willingly stepped down from the post after a decision in this regard was taken by the BJP in the “larger interest of Gujarat”.
