Balladur's trial has been scheduled for January 18 to February 19 in the Court of Justice of the Republic, a tribunal dedicated to hearing cases of ministerial misconduct.

The 91-year-old will be tried with his former defence minister Francois Leotard.

Balladur was charged in May 2017 with "complicity in misuse of corporate assets and concealment" over the sale of submarines to Pakistan in 1994 when he was premier and hoping to become president.

The claims came to light during an investigation into a 2002 bombing in Karachi, Pakistan, which targeted a bus transporting French engineers -- allegedly in revenge for non-payment of bribes.

Fifteen people were killed, including 11 engineers working on the submarine contract.

The Al-Qaeda extremist network was initially suspected of the attack, but the focus later shifted to the arms deal, with investigators probing whether the bombing was revenge for the non-payment of bribes secretly promised to Pakistani officials.

At the time he was charged, Balladur said he would challenge the charges as they failed to take into account that his campaign spending had been vetted by the authorities and that the alleged wrongdoing dated back more than two decades.

The case is one of several high-profile corruption cases ensnaring senior politicians in France, chiefly from the conservative camp.

Former president Nicolas Sarkozy, who had served as Balladur's budget minister, is also embroiled in several scandals, including suspected corruption involving a judge.
