Picking a new pope for Egypt’s Orthodox church could take months, officials say, allowing debate to gather pace among Christians over the political role the next leader should have as Islamists rise to power.

Pope Shenouda, who died on March 17, led the Coptic Orthodox church for four decades. He acted as the main political advocate for the nation’s Christians, who make up about a tenth of Egypt’s 80 million people, while Hosni Mubarak was in charge.

Since Mubarak’s ousting last year, Christians have become increasingly worried after an upsurge in attacks on churches, which they blame on hardline Islamists, although experts say more local disputes are often also behind them.

Shenouda’s death, aged 88, has added to those anxieties and left Christians wondering how to make their voices heard when the Muslim Brotherhood and other Islamists have swept seats in parliament and are likely to have control over writing a new constitution.
