The Egyptian cabinet, reacting to a public outcry, has amended a document proposing principles for a new constitution that would have shielded the army from oversight by parliament, said a cabinet minister.

The document initially gave the ruling military council exclusive authority to approve any legislation on the army's internal affairs, Tourism Minister Mounir Fakhry Abdel Nour told a news conference on Thursday.

'We took into consideration many of the remarks that we received and we corrected, deleted and added many articles,' Nour said. 'There were clear notes on Article Nine and Ten and they were amended in a way that responds to the demands of the objectors,' he added.

Another change proposed by the cabinet was that the military budget be put under the control of a body supervised by the president, he said.

Islamist and liberal parties walked out of a meeting with the government on Tuesday in protest against the document, saying it allowed the army to defy an elected government.

The military council took power after President Hosni Mubarak was overthrown by a popular revolt on February 11. Military men have ruled Egypt since a 1952 military coup and control a large swathe of the economy.

Official campaigning began on Wednesday for parliamentary elections whose winner will have a key role in drafting a new constitution, with Islamists, liberals and the army vying for votes in a poll marking the end of decades of strongman rule.
