Donald Trump may be lighting up Twitter with strange new words (like “covfefe”) and attacks on allies, but in the battle for most attentions per tweet, the US president is losing. The world leader whose original tweets generate the most retweets is Saudi Arabia’s King Salman, according to the latest “Twiplomacy” study by communications firm Burson-Martsteller. In terms of output, there is no contest: the Saudi king only tweeted 10 times during the period covered by the study: April 2016 to May 20 of this year. But those 10 tweets were each retweeted more than 147,000 times on average, dwarfing Trump’s 13,100 average retweets per tweet, said the study. “King Salman posts exclusively in Arabic without any visuals, but every tweet is a digital home run,” said the report which was based on an analysis of 856 official and personal Twitter accounts of leaders in 178 countries.
