Grillo backs Raggi plan to close capital's Roma camps.

Rome mayor Virginia Raggi has called on Italy's interior ministry for a moratorium on the arrival of new migrants in the capital, citing the "strong migratory presence and the continual flow of foreign citizens", according to Italian news agency ANSA.

In a letter to Rome prefect Paola Basilone, Raggi said she found it "impossible, as well as risky, to consider further reception facilities" which would have a "significant impact" on the city.

Raggi's request follows her plan to relocate the city's Roma camps, a move backed by Beppe Grillo, the leader of her party, the anti-establishment Movimento 5 Stelle (M5S).
