Hungarian leader Viktor Orban said on Wednesday he would propose that European Union states pay more into the EU budget to help cope with the refugee crisis and that Greece should allow other countries to defend its borders to slow the influx. Hungary lies in the path of the largest migration wave Europe has seen since World War Two and has registered more than 220,000 asylum-seekers this year. To stem the flow of migrants, Orban's right-wing government has built a fence on the Serbian frontier and is constructing another on Hungary's border with Croatia.
