evidence: Indian Prime Minister @NarendraModi is the third-most followed world leader with 42 million followers on his personal account and 26 million followers on his institutional account (@PMOIndia), which boasts the fourth-largest following. The official @POTUS Twitter account of the U.S. president and the @WhiteHouse accounts occupy the fifth and sixth rankings, with 23 and 17 million followers respectively. Turkey’s President Recep Tayyip Erdoğan (@RT_Erdogan) has more than 12 million followers. India’s Foreign Minister (@SushmaSwaraj), @QueenRania of Jordan and the Indonesian president (@Jokowi) complete the Top 10 list of the most followed leaders with more than 10 million followers each. [...] While the Twitter accounts of the @WhiteHouse and @POTUS are the two most popular among their peers, followed by 290 and 250 world leaders respectively, they are giving all other world leaders the cold shoulder. The Trump @WhiteHouse is mutually following the @Cabinet, @POTUS and @realDonaldTrump accounts, but the White House is no longer following Russian Prime Minister @MedvedevRussiaE nor the UK's @Number10gov accounts as the @ObamaWhiteHouse did.
