Mumabi, October 13: In a major setback to Raj Thackeray, six out of seven Maharashtra Navnirman Sena corporators in the Brihanmumbai Municipal Corporation on Friday joined the Shiv Sena. The move comes just a day after the Shiv Sena lost the Bhandup bypolls and the party wanted to bolster its position in the civic body.

“Six Maharashtra Navnirman Sena corporators joined Shiv Sena today,” Shiv Sena chief Uddhav Thackeray said.

The group of six corporators led by Dilip Lande has written to the Konkan divisional commissioner to allow them to form a separate group in the BMC, the Hindustan Times reported.

Condemning the action, MNS leader Bala Nandgaonkar said, “The Sena finally had to take the help of MNS. However these traitors will be taught a lesson.”

The MNS would write to the Konkan divisional commissioner to not allow this split, terming it a violation of anti-defection laws, sources said.

The Bharatiya Janata Party had also jumped in and complained to the state election commission that a major political party in the Mumbai civic body was trying to buy corporators. “Our ally in the BMC has tried to kidnap four councillors and they have been offered Rs 2-4 crore each. One such councillor is from Ghatkopar and his family has just informed me. That’s why I have written a letter to the Election Commission,” BJP MP Kirit Somaiya said.

With the joining of six MNS councillors, the Shiv Sena’s tally in the BMC will be now 90. It also enjoys the support of four independents. The BJP has 82 corporators (technically 83, but one of its sitting corporators died) and has support of two independents.
