The Irish Data Protection Commission (DPC) has warned Facebook over its planned integration of its chat services -- WhatsApp, Messenger and photo-sharing app Instagram, asking the social media giant to provide it with an "urgent briefing" on the proposals.

In a statement, the Dublin-headquartered Irish watchdog said it understood the plan was at a "very early conceptual stage". "While we understand that Facebook's proposal to integrate the Facebook, WhatsApp and Instagram platforms is at a very early conceptual stage of development, the Irish DPC has asked Facebook Ireland for an urgent briefing on what is being proposed," the watchdog said in a statement late on Monday.
