Sitaram Yechury, the CPI(M) leader, had a tongue-in-cheek explanation for Finance Minister Pranab Mukherjee ripping into Brinda Karat during the discussion on inflation in Parliament. According to Yechury, “The FM was talking about the Wholesale Price Index (WPI) but we were telling him to talk about the Consumer Price Index (CPI) which showed a sharp rise in food prices. As we mentioned CPI, he thought we were talking about the political outfit CPI. That might have angered him.”
