NEW DELHI: The political atmosphere in the capital continues to be turbulent as the Enforcement Directorate (ED), which interrogated Congress president Sonia Gandhi for six hours yesterday, instructed her to appear today as well. The Congress president was earlier questioned in the case on July 21.

Earlier on Tuesday, the Congress chief appeared before the ED for the second round of questioning. She rejoined the questioning after lunch.

Congress leader Rahul Gandhi along with several party leaders was detained by Delhi Police on Tuesday at Vijay Chowk during MPs' march to Rashtrapati Bhavan to protest against over "misuse of agencies" by the government.

Around 50 MPs along with Rahul Gandhi were detained from the North fountain near Parliament.

The ED had earlier summoned Sonia Gandhi on June 1 to appear on June 8 in connection with alleged money laundering in the National Herald case.

Sonia Gandhi could not appear for questioning on June 8 after testing positive and being hospitalised for COVID-19. The Congress leader had developed a mild fever on June 1 evening and was found COVID-19 positive upon testing the next morning.

After her discharge from the hospital, she had asked for more time to appear before the agency.

Last month the ED also questioned Rahul Gandhi for five days in the National Herald case.

The case to investigate alleged financial irregularities under the PMLA was registered about nine months ago after a trial court took cognisance of an Income Tax department probe carried out on the basis of a private criminal complaint filed by former Bharatiya Janata Party (BJP) MP Subramanian Swamy in 2013.
