Bengal Chief Minister Mamata Banerjee is unlikely to attend Prime Minister Narendra Modi's scheduled programme at Haldia in Purba Medinipore district on Sunday evening, a top official at the state secretariat said.

The exact reason for this uncertainty has not been specified, but the "insult meted out to her" on January 23, when Jai Shri Ram' slogans were raised at an event just before her speech, could be the cause, he said.

Modi is set to inaugurate four projects in Haldia in oil, gas, and infrastructure sectors.

“Tomorrow evening, I will be in Haldia, West Bengal. At a programme there, will dedicate to the nation the LPG import terminal built by BPCL. Will also dedicate to the .nation Dobhi–Durgapur Natural Gas Pipeline section of the Pradhan Mantri Urja Ganga project,” Modi said in a tweet on Saturday

"Madam (CM) is unlikely to attend this evening's programme at Haldia where PM Modi will be inaugurating projects," the official told PTI.

The TMC boss has also asked her party members to skip the programme, he added.

Mamata had on January 23 refused to deliver her speech at an event on the occasion of Netaji Subhas Chandra Bose's 125th birth anniversary, after a section of the audience raised 'Jai Shri Ram' slogans in the presence of the prime minister.

She had said that such "insult was unacceptable".

Sources in the Raj Bhavan said Governor Jagdeep Dhankhar is scheduled to attend Sunday's event.
