PANJIM: As the Louis Berger bribery scandal linked to the water and sewage consultancy project, in Goa, gets exposed, (and which we can call “GOA’S WATERGATE”), there is a very big question which could open a can of very big worms on the full nature of the amount of loan Goa finally received for this project. The difference in the value of Yen to INR between 2007 when the project was sanctioned and 2010 when money was disbursed, changed drastically and has potentially given Goa an addition of INR 3000 crore for the 22,806 million yen loan amount .
