Germany’s mainstream parties initially backed Chancellor Angela Merkel’s warm welcome for refugees but the mood has turned more critical, with practical worries about how to feed and house so many people setting the tone.

“In September alone, we registered more refugees than for the whole of last year,” Stephan Mayer, a lawmaker from the Bavarian Christian Social Union (CSU) party, told parliament, putting the figure at over 200,000.

His CSU colleague Joachim Herrmann, the Bavarian interior minister, said up to 280,000 may have entered German territory last month.
