European politicians from Socialist Democrat parties were convening in Paris on Saturday for high-level talks that were expected to address, in part, the European migration crisis.
French President Francois Hollande was hosting the meeting at the Elysee, where leaders including Italian Prime Minister Matteo Renzi, German Vice Chancellor Sigmar Gabriel and Austrian Chancellor Werner Faymann were expected to take part.
The meeting was aimed at defining the centre-left message on the influx of migrants and asylum seekers to Europe, which brought more than 1 million people to its shores last year, with more than 140,000 more following since January.
It was also expected that leaders would discuss other issues that have taken a back seat to the migration crisis, including spurring economic growth and investment.
Britain's planned referendum on an exit from the European Union, as well as a rise of populism that has seen right-wing parties gain in the polls across the bloc, were also expected to be discussed.
