Veteran actor Rajinikanth said on Monday there was a vacuum in Tamil Nadu politics and he will fill, adding that the state was set to witness "spiritual governance".

Rajinikanth unveiled a statue of late chief minister MG Ramachandran at a private medical college in Chennai in the presence of a huge crowd.

"I am confident I can give good administration" Rajinikanth told the crowd.

This is Rajinikanth's first major public engagement since he revealed his political intentions on December 31 last year. The actor had announced he would join politics and field candidates in all 234 assembly constituencies in the next elections.

The event came days after Kamal Haasan launched his political party Makkal Needhi Maiam.

Observers feel that by unveiling the statue of Ramachandran, popularly known as MGR -- also a matinee idol who held sway over the masses of Tamil Nadu, Rajinikanth is apparently seeking to invoke his legacy.
