The Danish government has agreed a deal with its main ally, the Danish People’s Party, to strengthen border controls.
The agreement allows a permanent customs presence between Denmark and Germany to check vehicles for illegal immigrants, weapons and drugs.
The Schengen Agreement bars border controls but this deal only allows customs to perform random checks.
The Danish Finance Minister, Claus Hjort Frederiksen said: “We will make investments in new IT equipment, in license plate identification equipment, which will make it easier to pursue wanted cars that are crossing the border.”
France has called for changes to the Schengen rules to allow countries to reinstate temporary border controls when their frontiers come under pressure from non-european Union migrants.
These changes are being considered by the European Parliament and the European commission.
