According to Twiplomacy, a study conducted by global public relations and communications firm Burson-Marsteller, US President is the most followed leader on Twitter followed by Pope Francis, Indonesia's President Susilo Bambang Yudhoyono, The White House and Modi.
"Since his election in late May 2014, India's new Prime Minister Narendra Modi has become the fifth-most followed world leader on Twitter, with 4,956,244 followers," the study said.
Modi skyrocketed to the fifth place, leaving behind Turkey's President Abdullah Gul and Prime Minister Recep Tayyip Erdogan at the sixth and seventh place, respectively.
They each have more than 4 million followers each.

According to the study, Obama has 43.69 million followers, Pope Francis has 14.09 million and Yudhoyono has 5.06 million followers.
The study said the "meteoric rise" of Modi and Indonesian President shows that leaders of the most populous countries have a clear advantage in garnering "a large army of dedicated followers".
Twiplomacy said it aims to identify the extent to which world leaders are using Twitter and how they connect on the network.
Earlier this month, Burson-Marsteller analysed 645 government accounts in 161 countries. Only 32 countries, mainly across Africa and Asia-Pacific regions, did not have any Twitter presence.
The study also revealed that more than 83 per cent of all United Nations (UN) governments have a presence on Twitter, and two-thirds (68 per cent) of all heads of state and government have personal Twitter accounts.
These include tweets like "India has won! The conquest of India. Good days are ahead", Malaysian Prime Minister's tweet about Malaysia Airlines flight MH370, the abdication tweet of the King of Spain and even more trivial Sochi Olympics bet between Canada's Stephen Harper and Barack Obama.
