European Commission head Jean-Claude Juncker on Wednesday staked his leadership on preserving the EU's passport-free Schengen zone, saying member states had to adopt controversial plans for a new border control force.
Juncker told the European Parliament in the eastern French city of Strasbourg that it was no "time for business as usual" as asylum seekers, mostly Syrians fleeing war, have flooded across the European Union's external border.
"We Europeans no longer have many borders. We have one and we have a shared responsibility to protect it," Juncker said.
"European border and coast guard is not the answer to a new need. European border and coast guard is there to repair a weakness of our Schengen system. We are completing what should have been done from the start," he said.
"Let me be absolutely clear that under my leadership, we will do everything to protect what we have built and to make it stronger and better," he said.
"We want to defend everything Schengen represents, and let me tell you that Schengen is here to stay!"
The Schengen accord, considered a core achievement for the bloc, provides for borderless travel across most of the 28-nation EU based on the principle of free movement.
The migrant crisis, which has seen some one million people flooding into Europe, mostly via Greece and Italy, has tested that commitment to the limit, with several EU states temporarily re-imposing border controls as they try to slow the influx.
On Tuesday, the Commission unveiled plans for a new border and coastguard force that could intervene, without the host country's consent if need be, to restore security.
Many member states baulked at that provision, with Poland rejecting the idea outright as an infringement of national sovereignty.
The Commission, the EU's executive arm, said the proposed new powers would be used sparingly and stressed the need for cooperation with member states.
Juncker made clear Wednesday he expected speedy agreement.
"We have no time to lose," he said, urging the Council of member states and parliament to treat the plans "as a matter of urgency."
EU leaders were due to meet in Brussels for a summit on Thursday and Friday to debate the border control plan and other means to tackle the worst migrant crisis since World War II. [AFP]
