Delhi Chief Minister Arvind Kejriwal has become the second-most-followed Indian politician on microblogging site Twitter, with over six million followers.

He crossed the six-million mark late on Wednesday.

"And ... @ArvindKejriwal crossed the 6 million mark on @twitter (sic)," tweeted Aam Aadmi Party (AAP) social media chief Ankit Lal.

The AAP chief trails Prime Minister Narendra Modi, who has over 16 million followers on Twitter.

Both leaders are widely known for utilising the power of social media.

Kejriwal, in his early days as a politician, used Twitter to garner support and donation from his followers and fans. He later started using it as a medium to connect with people.

Congress leader Shashi Tharoor is also among the most-followed Indian politicians on the microblogging platform.
