Cold war between the siblings – Sanjay Dutt and his sisters

The war continues….Sanjay Dutt and Manyata are not on talking terms with the two sisters. On January 5th Sanjay Dutt’s sister, Namrata celebrated her birthday and from that day they are not talking to each other. It seems this cold war has started after Sanjay entered in politics.
Latest issue that can be noticed was that Sanjay Dutt’s sisters, Namrata and Priya were not invited for Sanjay and Manyata’s wedding anniversary party on 10th Feb. It is also known that before the party Manyata was telling everyone that number of attendees of the party will be more then the Filmfare awards attendees.
Weird thing of all is that Namrata’s husband, Kumar Gaurav is Sanjay Dutt’s best friend. But he too was not invited to attend the party.
It is known that both the sisters of Sanjay have a pleasant relation with Manyata. Sanjay and Manyata attended the Christmas party at Priya’s house. Also, the two were invited for Namrata’s birthday on 5th January. But Sanju attended the party for at least 15 minutes and Manyata didn’t turn up for the party.
Last year when Manyata had thrown a party when Sanju was out of town Priya attended the party, but Namrata didn’t because she too was not in the town at that time.
Then what is the soar reason between the siblings because of which they are having such type of differences???
Earlier whenever such type of differences occurred, Sanju and the two sisters used to pick up the phone and would clear the matter. But this time this is not happening. Since Priya belongs to a different political party (opposition party), Sanju might be feeling awkward to talk to her, but why didn’t he call Namrata then???
