Egypt's Illicit Gains Authority on Sunday froze the financial assets of Mubarak-era prime minister Ahmed Shafiq and his three daughters due to 'inexplicable' increases in their wealth.

Shafiq's trial on graft charges will begin on 2 December.

Shafiq was put on Cairo International Airport's watch list on 29 August. The names of his daughters are expected to be added to the list on Sunday.

Shafiq, for his part, responded to the news by promising "an aggressive reaction."

He described the move as "an impulsive reaction that only aims to hinder my political career."

Speaking to Al-Ahram's Arabic-language news website, Shafiq pointed out that, as a candidate in Egypt's recent presidential elections, "my financial position was reviewed and no wrongdoing was found therein."

Immediately following his loss to Muslim Brotherhood candidate Mohamed Morsi in Egypt's first post-Mubarak presidential election this summer, Shafiq travelled to the United Arab Emirates. It was later revealed that the former presidential hopeful planned to remain in the UAE for "security reasons."
