Many in the Bharatiya Janata Party (BJP) top brass are yet to pay a visit to senior leader and External Affairs Minister Sushma Swaraj, who was admitted to New Delhi's All India Institute of Medical Sciences with chest congestion and fever last week. Among the party bigwigs who have visited Swaraj are Prime Minister Narendra Modi and Madhya Pradesh Chief Minister Shivraj Singh Chouhan. Swaraj is a rare BJP senior leader who enjoys a rapport with Congress President Sonia Gandhi and her son Rahul Gandhi. This, despite having fought a bitter battle against Sonia Gandhi in Karnataka's Bellary in the 1999 Lok Sabha elections and even taking an oath that she would get herself tonsured if the Congress president were to become the PM. No wonder, Rahul Gandhi, who is the Congress vice-president, called on her a couple of days after the PM.
