Traditionally, Indian prime ministers have taken their Cabinet colleagues along on overseas visits. But Prime Minister Narendra Modi is not known to let his ministers accompany him on his foreign trips, barring a few occasions. A couple of days ago Minority Affairs Minister Najma Heptulla was asked why she did not travel with the Prime Minister to Saudi Arabia earlier this month. Heptulla said she would have loved to go, "but what to do when the PM loves travelling light?" Modi is also known to keep a punishing schedule on his visits abroad.
