No source can be CREDIBLE enough for a person who has put a blindfold around his eyes.
This is a NEUTRAL source, not BJPs, not Congress, not any other Indian Party.
But than you are obviously not believing it.
The figures which you are calling as made-up are neutral ESTIMATES of the income of Ms. Gandhi.
So, what you think she will come out in open an say that she has more money than Mukesh Ambani??
Have you heard about Swiss bank accounts?? Why do you think they are so afraid to bring back the money??
Mayawati who was the CM of UP for 5 years from 2007-12, nearly double her assets in this tenure from 52crores to 112 crores:
Mayawati assets doubled to Rs 112 crore as chief minister - Times Of India
this were her declared assets, only God knows what were her undeclared assets.
Now if just a CM of just one state (of 28) of India can double her assets in just 5 years of rule, than Gandhis are ruling whole INDIA for around 50 years, what do you think there net worth would be??
In 1991, a Swiss magazine disclosed that Mr. Rajiv Gandhi has $ 2.5 billion in swiss accounts, this is 2013, complete 22 years, do you want to believe that there net worth has actually decreased when entire INDIAN pop. income was rising??
chk this out, if you find it as CREDIBLE enough:
