In a major relief for Kalanithi Maran, as many as 33 channels of his Sun TV Network are set to get security clearance.

The development comes after the Attorney General gave his opinion to the Information & Broadcasting Ministry that the Home Ministry denying security clearance to Sun TV is wrong.

The Home Ministry had denied clearance on the grounds of an Enforcement Directorate and the Central Bureau of Investigation (CBI) probe against Maran.

Kalanithi Maran had argued that while most of the TV companies have criminal cases pending against them or against their directors or promoters, only his company was singled out and security clearance refused.

Earlier, sources had said that the Home Ministry had no plans to reply the letter written by Maran where he had said his company was never involved in any anti-national or criminal activity and there was no justification for refusal of the clearance to his television channels.

Home Ministry officials were also suspecting that the Sun Network may try to cite the relief the company got from the Madras High Court after the Centre withdrew the Multi System Operator licence for Kal Cables owned by the Maran families.
