Congress President Sonia Gandhi and Vice President Rahul Gandhi have returned from the United States 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.

The Congress President had travelled to the US on March 8 for a health check-up, while son Rahul joined her last week.

Now that Rahul has returned, the Congress brass will brainstorm over the results of assembly elections in the five states, which proved to be a mixed bag for the party, some party leaders indicated.

But the Congress failed to form governments in Goa and Manipur despite emerging as the single-largest party in both states.

Some party functionaries have also been calling for Rahul's elevation as the party President.
