Chief minister Mamata Banerjee who along with Speaker Biman Banerjee were among those who offered flowers at Basu's portrait, said that the Left Front members had not shown courtesy to a great leader belonging to the CPI(M).
Leader of the Opposition Surya Kant Mishra, belonging to the CPI(M) said that Jyoti Basu's birthday would be observed on the original date of July eight.
Left Front members had earlier abstained from attending the advanced birthday observation of first state chief minister of the state Bidhan Chandra Roy in the assembly on June 29, though his actual date of birth was July one which was a Sunday.
Tributes were also paid to Hindu Mahasabha founder Shyama Prasad Mukherjee in the house today on his birthday.
