Kohima, Jan 04 : Nagaland Governor K Shankara Narayanan on Friday said that the imposition of President's Rule in the State was necessary due to the possibility of horse-trading and the insurgency-hit state’s special security needs.

Narayanan said that there was no option but to impose President’s Rule under the provisions of Article 356 and let the state hold fresh assembly elections.

On Thursday, President Pratibha Patil signed the recommendation of the Union Cabinet to dismiss the Neiphiu Rio Government and impose Central rule.
