Prime Minister of India Narendra Modi has wished superstar Rajinikanth on his 70th birthday on Saturday."Dear @rajinikanth Ji, wishing you a Happy Birthday! May you lead a long and healthy life," Modi tweeted.

Rajinikanth had recently announced his decision to launch a political party and contest the upcoming Assembly elections in Tamil Nadu. Soon after the announcement, the actor-turned-politician met and sought blessings from elder brother Sathyanarayana Rao, sources close to him said.

'Thalaivar' (meaning leader), as the superstar is fondly addressed by fans, had been mulling political entry for many years.
