Taking on Law Minister Somnath Bharti following the vigilante-style rounding up and alleged manhandling of some African nationals in a midnight raid last week, Jaitley said his approach appeared to be racist.
"He has created a serious problem with African nationals staying in Delhi," he said, adding that the AAP had become a victim of its own unconventional style.
"Mobs can't take decisions. They can at best be populist. The party's performance in government is becoming embarrassing by the day."
Raising questions on the agitation, Jaitley asked: "Is the planned dharna for one day a ploy to fracture its non-transparent arrangement with the Congress? Is the AAP looking for a way out of the government and get back to the streets? Or is it exploiting the non-preparedness of the Congress and the home minister yielding to the pressures of the AAP?"
