However, Rahul's absence left the party to field questions about his location and return on a daily basis. "Every individual has a right to privacy and we must respect that. Our vice-president did not escape or disappear... His one month absence seems to have become a problem in India," AICC spokesman P C Chacko said, yet again on Wednesday .
For the Congress vice-president, the return coincides with an increasing frequency of public comments from members demanding that Sonia Gandhi continue as party chief. Former Delhi chief minister Sheila Dikshit's remarks on Tuesday followed similar views aired by former MP Sandeep Dikshit and former Punjab chief minister Amarinder Singh.

A harried Congress on Wednesday sought to impose a gag order on controversial comments. "Senior members should refrain from making open comments. They should not create unnecessary controversy as interested sections want to create confusion," Chacko said, adding that any suggestion of differences between Sonia and Rahul were "completely wrong".
Rahul will attend the farmers rally in Delhi on April 19, a party protest against the land acquisition bill of the Modi government.
