The joint government investigative wings today summoned former education minister Dora Siliya over unknown corruption allegations.

Siliya who is also Petauke Central member of parliament arrived at the former Task Force offices in Kabulonga around 14:00 hours and went straight into the interrogations room where she was quizzed for about an hour.

Siliya's lawyer Lubinda Linyama was also seen at the Task Force offices but sources say he did not speak to journalists who were present.

The interrogation of Siliya comes at a time of heightened tensions between the government and opposition parties, including an indictment presented before the Commonwealth and a campaign to remove immunity of the former president, Rupiah Banda.

Siliya, who is also the spokesperson for the former ruling party MMD, was accompanied by youth leader Bowman Lusambo and MMD President Nevers Mumba's special assistant Raphael Nakachinda.

The government's varied allegations against Siliya have persisted for several years without any result. She is accused of wrongfully participating in the privatization of ZAMTEL, a sale which President Michael Sata reversed shortly after assuming office.

She is also accused of disregarded tender procedure in the procurement process of a Radar at the Kenneth Kaunda International Airport.

The former minister is also awaiting the final Supreme Court ruling in the matter where her seat as Petauke Member of parliament was challenged by the PF government through a petition.
