Highly placed sources in the party said that Tharoor had sought an appointment with Patel two days ago.
    
While the issue of registration of a murder case in Sunanda's death came up for discussion briefly, the two leaders also discussed prevailing political scenario and recent developments in Kerala, from where Tharoor is elected to Lok Sabha.
    
There is little likelihood of any meeting of Tharoor with Sonia or Congress vice president Rahul Gandhi in days to come, the sources said, adding nothing has been decided on further course of action against Tharoor vis-a-vis party affairs so far.
   
The Congress had earlier said that there must be an impartial inquiry into the matter.
    
Party general secretary Janardhan Dwivedi had two days ago said that there should be no discrimination either in someone's favour or against in the investigation.
    
Earlier in the day, Tharoor said he would cooperate in the investigation, even as Delhi Police said it will not question him as of now.
    
"It is my duty to cooperate with the police investigation and not to undermine the probe in any way," Tharoor said.
    
51-year-old Sunanda was found dead in a five-star hotel in South Delhi on the night of January 17 last. Delhi Police had on last Tuesday registered a case of murder in connection with Sunanda's death under Section 302 of IPC on the basis of an AIIMS medical report that concluded that her death was unnatural and due to poisoning.
