The appeal, aimed at Iraqi prime minister Nouri al-Maliki, was made by a Christian deputy, Yunadim Kana, and outlined in an interview with the Arab language daily al-Hayat.
Kana's idea comes after Iraq's president Jalal Talabani's appeal to Christians earlier this month that they move to Iraq's autonomous northern Kurdistan region as a means to escape extremist attacks against them, until the government can assure their security.
In the interview, Kana indicated the already largely Christian area of Sahl Ninve, east of the city of Mosul, which that spans dozens of kilometres and where the villages are already almost totally occupied by Christians.
Earlier this month, a Dutch member of parliament Joel Voordewind, called for an autonomous region to be created for Christians in northern Iraq, around the Nineveh Plain, where around 100,000 Chistians have taken refuge since 2003. The region shoudl be governed and secured by its police and militia, he said.
Many of Iraq's approximately 500,000 remaining Christians are living in fear of their lives after the continuing attacks and death threats unless they leave the country.
