This has been revealed in a study by Burson-Marsteller, a leading global public relations and communications firm.
PM Modi with more than 31 million fans on his personal Narendra Modi page and 10.1 million fans on his institutional PMO India page, said the study report.
As far as fan following on Facebook is concerned, US President Barack Obama is the most popular leader in the world. The US President has over 46 million likes on his Facebook page.
The study also adds that PM Narendra Modi took a lead over President Obama in terms of the number of interactions (post likes, comments and shares).
Modi has the most interactive fans, with more than 200 million interactions in his Facebook ‘community' in 2015 (the total number of post likes, comments and shares), more than five times as many as Obama. However, the White House's posts, while attracting far fewer likes than Modi, are nevertheless shared more frequently.
Over the past eight years, Facebook has become the platform of choice for world leaders and governments to engage with their voters and constituents.
