Ten district-level Trinamul leaders, including a panchayat samiti chief and two panchayat pradhans from the Shahid Matangini block in East Midnapore, were suspended for three years by the ruling party’s district core committee for “anti-party activities” after a meeting at the Tamluk party office on Saturday.

The suspensions came in the wake of reports that they were acting against party interest by virtue of being allied to turncoat Suvendu Adhikari.

Among those are block panchayat samiti sabhapati Dibakar Jana, his wife Tanusree, panchayat pradhan Shiladitya Adak and panchayat pradhan Minati Pattanaik.

Trinamul district party president and water resources minister Saumen Mahapatra said on Saturday that another list of “possible or likely” party workers considered close to “a leader of our party who joined the BJP” (read Adhikari) had been drawn up in 25 blocks in the district.

“The list has at least 150 names...We have many leaders in the Trinamul in name only but who actually work for a leader of our party who joined the BJP. They need to be identified immediately, and we hope the steps taken in Shahid Matangini block will send a strong message to all,” he said.

Hooghly BJP MP Locket Chatterjee called on Adhikari’s father and Trinamul MP Sisir Adhikari and his son Dibyendu at their Contai home on Saturday afternoon, with sources saying Sisir received a formal invitation to the PM’s rally in Contai on March 24.

“Locket Chatterjee stayed for over half an hour and had lunch with them,” said a source.

Asked about the development, district president Mahapatra said the party was “taking note”.

"Who is going where and talking to whom is all in our knowledge. The state-level leaders are being informed as well," he said.

"Sisir and Dibyendu have been inactive for all pre-election activities and are being reported for the same," the minister added.

Chief minister Mamata Banerjee is slated to be back in Nandigram on March 19, at a two-delay from her earlier schedule owing to the injury she suffered in Nandigram on March 10. She will address rallies at Egra, Potashpur and Mechheda.

"Security will be much enhanced this time around," said a police source, adding that district administration was looking into the same.
