Calls are mounting for Italy's president to allow the public to follow his testimony in a trial of a former government official accused of negotiating with Mafia bosses to end terror bombing in the 1990s.

President Giorgio Napolitano, 89, is set to testify behind closed doors in the presidential palace Tuesday when the trial moves from Palermo to Rome for the day.

Editorialists and opposition politicians Monday demanded the media, including live TV, be allowed to cover Napolitano's testimony.

The Palermo court is trying former Interior Minister Nicola Mancino for allegedly negotiating with the Mafia following 1993 bombings in Rome, Florence and Milan. Napolitano has said he knows nothing about alleged negotiations. An intercepted phone call between Mancino and a now-deceased Napolitano aide prompted prosecutors to seek the president's testimony.
