CAIRO - Egypt's new cabinet met for the first time on Wednesday with security high on its agenda and under attack from the Muslim Brotherhood and others who want it purged of ministers appointed by ousted president Hosni Mubarak. In preparation for polls that military rulers have promised to hand over power to civilian rule in six months, activists announced the forming of a new political party on Wednesday. The Brotherhood and other political groups have called for another million-man-march on Friday to fill Cairo's central Tahrir Square, which was the nerve-centre for opposition to Mubarak's 30-year iron rule, to call for a new cabinet. Banned under Mubarak and playing an increasingly active role in Egyptian political life since the 18-day uprising that toppled Mubarak, the Brotherhood wants the lifting of emergency law, freeing of political prisoners and a purge of the cabinet. The cabinet will discuss security issues in the post-Mubarak era and the provision of basic foods and subsidies on Wednesday, political sources said. Despite political pressure, there are unlikely to be further changes in the cabinet, they added.
