Rajya Sabha MP Kapil Sibal on Monday hit back at Prime Minister Narendra Modi over his 'quit India' jibe at the opposition, saying "we want a united India" where those who "protect and hide corruption must quit".

Sibal's remarks came a day after the prime minister, while addressing an event to lay the foundation stone for the redevelopment of 508 railway stations, accused the opposition of playing "negative politics" and said now the entire country is rooting for corruption, dynasty and appeasement to 'quit India'.
