David Cameron will visit Paris on Monday after military action against Islamic State (IS) in Syria grew a step closer following approval by the United Nations Security Council for plans to redouble its efforts to prevent further attacks from extremists.
The Prime Minister, who is seeking to bolster support for UK air strikes in Syria, will meet for talks with French president Francois Hollande at the Elysee Palace.
The council backed a French-sponsored resolution designed "to combat by all means this unprecedented threat", saying IS "constitutes a global and unprecedented threat to international peace and security".
It was hailed as an "important moment" by Mr Cameron as he seeks backing for UK air strikes in Syria.
Mr Cameron said the vote "shows beyond doubt the breadth of international support for doing more in Syria and for decisive action to eradicate" IS, which he described as "this evil death cult".
A Number 10 spokesman said: "The Prime Minister will travel to Paris on Monday morning for talks with President Hollande at the Elysee. They are expected to focus on counter-terrorism co-operation and the fight against Isil in Syria and Iraq."
