In India every meeting seems to be controversial. Now it is about the meeting on of Prime Minister Narendra Modi with former Prime Minister Manmohan Singh. Rahul Gandhi says Modi called Manmohan Singh to learn about economy. BJP sources may say that Manmohan Singh wanted to get escape from the 2G embroil and hence met PM.
It is sure that something is there. But both the present PM and the former PM may not divulge.

The point is what they discussed.
