KOLKATA: On Wednesday, Bengal Chief Minister Mamata Banerjee stood by her new resolution of a closer cooperation with the Congress, which is facing BJP attack after party chief Rahul Gandhi's brother-in-law Robert Vadra was questioned by the authorities in a money laundering case.

Asked about the questioning, Ms Banerjee brushed it off. The Bengal Chief Minister in what is seen as a reciprocation to the Congress support earlier this week said that "There is no serious case, nothing, just sending the notice casually to everybody. So we stand together, we are united," Ms Banerjee further added that "They (centre) are doing it deliberately ahead of the polls,".

Here,though the ties between Rahul Gandhi and Ms Banerjee were seen as lukewarm, the Congress chief had dialled Kolkata when Ms Banerjee declared a sit-in protest against the Centre after what she called the "misuse" of the CBI.

However, Robert Vadra was questioned for over four hours in a case involving purchase of a series of properties in the UK. Mr Vadra, who is also the son-in-law of Congress leader and UPA chairperson Sonia Gandhi, has said he is being subjected to "unwarranted, unjustified and malicious criminal prosecution" for political reasons.
