Intensifying attacks on Congress Party, the Gandhi family and real estate giant DLF, Arvind Kejriwal has released documents that allegedly show illegal links among Sonia Gandhi's son-in-law Robert Vadra, DLF and the Haryana government.

Kejriwal, activist-turned-politician who has yet to name his recently launched political party, showed documents that purposely showed that the Congress-ruled Haryana state government had provided DLF with large favour over the years and added that the favourable treatment was given due to DLF's links with Sonia Gandhi's son-in-law Robert Vadra.

A few days back, Kejriwal had accused the country's biggest real estate company of providing unsecured interest-free loans worth Rs 55 crore to Vadra's companies, which Vadra used to buy apartments in some of DFL's premium residential projects.

He questioned the Vadra's dealing with DLF saying, "Is it a normal business practice to give an advance of 90% of the amount of transaction and let it remain with the seller for more than two years without even bothering to take possession of the land?"

The India Against Corruption (IAC) founder also charged Sonia Gandhi's son-in-law of profiting around Rs 500 crore from his dealings with DLF. In the recent attack, he also accused two other real estate companies, viz. IndiaBulls and BPTP of having investments by several politicians.

DLF refuted the allegations, claiming it hadn't sought or enjoyed any special favours from the state government. Congress called the allegations a publicity gimmick.
