What did Sonia discuss with Sushma Swaraj at lunch table in Johannesburg

Present at the lunch table were Sushma Swaraj's daughter Bansuri, BSP  leader Satish Chandra Mishra and Commerce Minister Anand Sharma.
 
Sushma Swaraj sat on the right and her daughter sat on the left of Sonia Gandhi.  CPI-M leader Sitaram Yechury joined them after a while.

Swaraj Swaraj refused to reply to any query on politics in India, specially the hung verdict in the Delhi Assembly polls.

She was happy to comment on Mandela's memorial service, saying it was a "momentous" occasion and the biggest test of the late South African leader as a great unifying force.

"Here was a man who struggled so much without even being sure where his struggle would lead the South Africans to," she said.
