Special security arrangements have been made on Saturday in and around Patiala House courts here ahead of the appearance of Congress President Sonia Gandhi and Vice President Rahul Gandhi, sources said.
A team of Special Protection Guard (SPG), Border Security Force, and anti-bomb squad has been deployed inside and outside the court premises.
The court had ordered Sonia and Rahul Gandhi to appear on Saturday in connection with Bharatiya Janata Party (BJP) leader Subramanian Swamy's complaint in the National Herald case.
On June 26 last year, the trial court issued summons to the Congress leaders on Swamy's complaint about "cheating" in the acquisition of Associated Journals Ltd (AJL) by Young India Ltd (YIL), a firm in which Sonia and Rahul Gandhi each own a 38 percent stake.
The Delhi High Court last week dismissed the plea of the Gandhis to quash the summons issued to them by a trial court.
The trial court later fixed December 19 for hearing the case.
