Egyptians turned out in large numbers on Wednesday for a second round of parliamentary elections, with Islamic parties looking to boost their already overwhelming lead.As in the first round, voting was largely peaceful, but a gunfight between supporters of rival candidates closed a polling station on Cairo’s outskirts, a security source said. No one was killed. Seven people were detained.In another shooting, one person was seriously wounded in a village near Suez city, east of Cairo, after a dispute apparently unrelated to the election.The military will still appoint the government, but the next parliament will have legislative powers. It will also pick a 100-strong assembly to write a constitution that will define Egypt’s political framework after decades of autocratic rule.The constitution is already the focus of a tussle between Egypt’s newly-assertive political class and the ruling generals.
