On Wednesday evening the red-green government announced it was introducing police checks at some border points starting at noon on Thursday, and said this was because of a request by the Migration Agency.
"Now it’s for 10 days, then it can be extended to 20 days, but if it is to have any effect it has to continue for longer," says Anders Danielsson to Swedish Radio P1-morgon.
The controls will affect crossings between Sweden and its neighbours to the south, Germany and Denmark.
"We have had as many asylum seekers in the last two and a half months as during the whole of last year. We don't manage to register all," says Danielsson.
