Arvind Kejriwal crossed the six-million mark late Wednesday.
“And … @ArvindKejriwal crossed the 6 million mark on @twitter,” AAP’s social media chief Ankit Lal tweeted.
The Aam Aadmi Party chief trails Prime Minister Narendra Modi who has over 16 million followers on Twitter.
Both the leaders are widely known for utilising the power of social media.
Arvind 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 world.
