Sonia returns from US after health check-up (Lead)

New Delhi, March 24 : Congress President Sonia Gandhi and Vice President Rahul Gandhi have returned from the US where Sonia Gandhi had gone for health check-up, the party said on Friday.

"Congress President and Vice President have returned to India. Thanks to all the countrymen and Congress people for their good wishes," party's spokesperson Randeep Surjewala said in a tweet.

Sonia Gandhi had left earlier this month for the check-up. 

With the return of top two leaders, the party is now expected to hold a formal introspection about its performance in the assembly polls to five states and its massive loss in Uttar Pradesh and Uttarakhand. 

Asked about organisational changes, party spokesperson Abhishek Singhvi told reporters that these were on the cards. 

"Both of them are back and we hope and trust that as far as Sonia Gandhi is concerned, she is hale and hearty . I think you should be fair enough to give us all a chance to breathe. especially those who have returned yesterday. That (change) is definitely on the cards but you do not have to put timer switch to it," he said. 

There have been suggestions by party leaders that Rahul Gandhi should be elevated as party chief.
