Italy will not take part in the intergovernmental conference in Marrakech next month to adopt the United Nations global compact on safe and orderly migration, populist premier Giuseppe Conte said Wednesday.

"The Global Migration Compact is a document that raises issues and questions that many citizens have strong feelings about," Conte said.

"Therefore, we consider it right to put the debate in parliament and subject any final decision to the outcome of that debate, as Switzerland has done.

"So the government will not participate in Marrakech, reserving the option to adopt the document, or not, only once parliament has expressed its opinion".

Poland, Hungary, Austria and United States are among countries which have already said they won't support the non-binding compact, which is due to be formally approved at a 10-11 December meeting in Marrakech, Morocco.

The Global Compact for Safe, Orderly and Regular Migration,was finalised under UN auspices in July.
