Noting “chaos” on the Greek island of Kos, where thousands of migrants mainly from Syria and Iraq have turned up in recent weeks, Mueller said Switzerland needed to refocus on the issue of migrants.He said too many people have been granted permanent refugee status in Switzerland in recent years and not nearly enough have been ordered to return home. “People displaced by war should still be taken in but only with the aim of sending them back later when the situation in their country of origin allows it,” Philipp Mueller, leader of the influential center-right FDP party, told the Schweiz am Sonntag paper. Switzerland, known for its tame political climate, goes to the polls on October 18.As in the rest of Europe, migrant and refugee policy has increasingly become a source of debate in the country.Justice minister and current Swiss President Simonetta Sommaruga earlier this month said it was “unthinkable” that Switzerland would return people to Eritrea, which is led by authoritarian regime. A leading Swiss politician has called for the return of Sri Lankan asylum seekers in Switzerland as the island is now at peace, the AFP news agency reported.He said people fleeing conflict should only receive temporary protection in Switzerland, calling for a rethinking of the country’s approach to asylum seekers in an interview published today. He specifically cited Sri Lanka, where a 25-year civil war ended in 2009.“Asylum-seekers are still not being sent back there although the country has become a tourism destination for Swiss people. That is absurd,” Mueller said.In a review of Switzerland concluded this week, the United Nations Committee against Torture voiced concern that the federation “is not sufficiently considering” circumstances in the country of origin before sending migrants home. The U.N. panel specifically noted two reported cases of ethnic Tamils being subjected to torture after being forcibly returned to Sri Lanka. “People attempting to enter for economic reasons must be rejected,” Mueller added. She was responding to criticism from the right-wing Swiss People’s Party that the government’s handling of Eritrean migrants was too lenient, a complaint echoed Mueller.
