Modi had written personalised letters to celebrities, industrialists and noted personalities to enlist their support for the initiative.

A day after the Arvind Kejriwal-Kamal Haasan lunch date on Thursday, superstar Rajinikanth today extended his full support to Prime Minister Narendra Modi's 'Swachhata Hi Seva' movement, adding that "cleanliness is godliness".

"I extend my full support to our honourable Prime Minister Narendra Modiji's Swachhata Hi Seva mission. Cleanliness is godliness," Rajinikanth, who is being wooed by the BJP in Tamil Nadu, tweeted.

Earlier this week, Modi had written personalised letters to celebrities, industrialists and noted personalities to enlist their support for the initiative.

Quoting Mahatma Gandhi, Modi had said Swachhata is for each of us to practice. He also said the days leading up to Gandhi Jayanti on October 2 be about "encouraging widespread participation in cleanliness initiatives across the country."

Incidentally, Rajinikanth's tweet comes a day after the high-profile lunch date between another Tamil star Kamal Haasan and Delhi Chief Minister Arvind Kejriwal in Chennai.

At a press conference following the meeting, Kejriwal invited Haasan to join active politics to fight corruption and communalism. On his part, Kamal Haasan said it was an honour to learn that Kejriwal wanted to meet him. His residence was always politically active during his father's time though he himself had kept away from it, he said.

As the factional fight within the ruling AIADMK intensifies in Tamil Nadu, a number of players including the BJP and the Aam Aadmi Party have been looking to fish in the troubled waters in the state.
