As the Congress today tackled a fiery meeting of its top decision-making body that saw Sonia Gandhi announcing her decision to resign as chief after a controversial letter written by over 20 leaders, Shatrughan Sinha delivered cautious criticism of the party he joined last year. "I have not even completed two years in the Congress but from what I see, there is only one complaint – a platform where one can voice one's concern is often not visible," Shatrughan Sinha, 74, told NDTV as the Congress Working Committee held an online meet to discuss the letter.
