Saying that Modi was “fast asleep” and criticising the way Jaitley broke the news on social media, Gandhi described the situation as "crazy".
"The brightest flee the sinking ship, as the invisible hand of the RSS steers it onto the rocks. Meanwhile, Captain DeMo is fast asleep. It's crazy out there!," Gandhi tweeted.
The Congress president questioned whether Jaitley, who held the finance portfolio before undergoing a kidney transplant surgery in mid-May, continued to be the finance minister.
"Ex? FM is locked in his room, breaking news on Facebook. BJP treasurer has the keys to the Indian economy," he added.
