Mamata had joined PM Modi and Bengal governor Jagdeep Dhankar at the Victoria Memorial event orgainsed to mark Netaji's birth anniversary. When it was Mamata's turn to give her speech, a section of the crowd indulged in sloganeering and chanted "Jai Shri Ram." The organisers requested the crowd to maintain silence and allow Mamata Banerjee to give her speech. But a furious Mamata took strong exception to this and said "If you invite someone to a govt programme, you should not insult them."
