MDMK leader Vaiko faces legal action for accusing DMK chief and Tamil Nadu Chief minister M. Karunanidhi of "arranging" the attack on the office of Tamil filmmaker and Sri Lankan Tamil sympathiser K. Bharathiraja.
Vaiko made the charge against Karunanidhi at a public meeting here on May 29, alleging sarcastically that the "attack on Bharathiraja's office had the blessings of the chief minister".
Some masked men attacked Bharathiraja's office and damaged computers and other office equipment on May 17.
Enraged, Karunanidhi slammed a legal notice on Vaiko, seeking an unconditional apology for defaming him.
The state counsel's notice said Vaiko should apologise for his remarks within 24 hours or face civil and criminal actions for defamation.
However, MDMK lawyer Devadoss told HT, "We are yet to receive the copy of the notice. Only after we get it, can we frame our response."
