Brussels, January 20 - European Commission President Jean-Claude Juncker on Wednesday requested an extraordinary summit of European leaders to address the migrant crisis. Germany told Italy Wednesday that a swift accord was needed to free up a three-billion-euro package of aid to Turkey for migrants which Rome is blocking because of the way it is being funded. "We deem it necessary to quickly conclude the accord," said German Chancellor Angela Merkel's spokesman Steffen Seibert in Berlin. To this end a January 29 meeting in Berlin between German Chancellor Angela Merkel and Italian Premier Matteo Renzi will be "an important opportunity" to meet "an important partner", Seibert said, answering a question on whether the meeting might help resolve the dispute on migrant funds for Turkey. Italy wants to see more of the aid, aimed at helping Turkey cope with a huge influx of asylum seekers from war-torn Syria and Iraq, funded by the EU rather than by member States. The issue is one of several which have fuelled a row between Rome and Brussels. Also on Wednesday, Juncker said there will be no negative fallout from the recent "lively exchange" between Italy and the European Commission. "Relations between the Commission and the Italian government, between commissioners, and between myself and my Italian colleagues and the premier (Matteo Renzi) are good," he said. "There was a lively exchange, but this is normal in times of democracy and will have no consequences," Juncker said.
