The Danish system What are the policies the UK is hoping to emulate?

Of all the measures introduced to deter people from seeking asylum in Denmark over the past decade, the impermanence of refugees' status is often cited as being the most effective.

Before 2015, refugees were initially allowed to stay in Denmark for between five and seven years, after which their residence permits would automatically become permanent. But 10 years ago, when more than a million people arrived in Europe fleeing conflict and repression, most from Syria,

Afghanistan, Iraq and Eritrea, the government changed the rules.

Since then, temporary residence permits have only been granted for one to two years at a time and there is no longer any guarantee of getting a permanent visa. To gain permanent status refugees have to be fluent in Danish and must have had a full-time job for several years.

"It's about the attitude and feeling of being here as a visitor on a temporary basis. You don't know where your future is going to be," said Michala Clante Bendixen, who runs Refugees Welcome Denmark and is the country coordinator for the European Commission's migrant integration hub.
