Denmark's centre-right government yesterday (11 May) agreed to introduce border controls at its ports and airports, as well as along its only land border with Germany and its bridge to Sweden. The European Commission asked for additional information and said it would not accept any roll-back of the Schengen treaty.

The Danish government caved in to the demands of the Danish People's Party, a populist and anti-immigration party that has been holding up approval of its 2020 economic plan.

"We have agreed on permanent border controls which we will implement as soon as possible," Finance Minister Claus Hjort Frederiksen said on TV 2 News after the border deal had been struck with the Danish People's Party and the small Christian Democratic Party.
