In a statement here, he said President's rule should be imposed in the state if the Tamil Nadu Government fails to follow the directions.
"I demand that the Union Government send Tamil Nadu Government a direction under Article 256 of the Constitution to stop interfering in India's foreign policy on Sri Lanka and also ensure safety of Sinhalas in the state," he said.
"If the Chief Minister fails to follow the direction then President's rule should be imposed in the state," Swamy said.
The Janata Party president also demanded that the Madhya Pradesh Government arrest MDMK chief Vaiko if he protests against Sri Lankan President Mahinda Rajapaksa's visit to the state later this month.
