The Enforcement Directorate, which questioned Congress interim chief Sonia Gandhi in the National Herald case on Thursday, kept two doctors and an ambulance on standby as a humanitarian gesture, agency sources said.

The central agency also allowed Sonia Gandhi's daughter and party leader Priyanka Gandhi Vadra at its office.

The sources said that Sonia Gandhi was asked over two dozen questions "after which she asked to go home for her medication".

They said ED allowed this and it will call her for interrogation again on Monday. Congress held protests in different parts of the country over ED summoning Sonia Gandhi with party leaders accusing the government of "political vendetta" against the opposition.

Party leader and Rajasthan Chief Minister Ashok Gehlot had said earlier in the day the ED should have gone to Sonia Gandhi's residence if they wanted to question her. The ED had on June 1 summoned Sonia Gandhi to appear on June 8 in the case for the first time in connection with alleged money laundering in the National Herald case. Sonia Gandhi could not appear for questioning after testing positive for COVID-19
