The Dublin Regulation is the regulatory framework that governs which EU country is responsible for a person seeking asylum.

The basic principle is that the first country you come to as a migrant is the one you should seek asylum in. 

- The latest version of the regulation came into force in 2013, but countries such as Italy and Greece, which are the countries that many come to first, believe that they have had to take far too much of the responsibility.

A lot of problems are associated with the regulation, says David Boati, SVT's European correspondent in Morgonstudion. 

The regulation will now be replaced by a new European migration system, as announced by European Commission President Ursula von der Leyen during a speech in the European Parliament. 

- The proposal for a new system is far from clear.

The EU has struggled with this since the crisis in 2015, but has not really achieved this with a common asylum policy, says David Boati.

Can lead to debate

This could lead to a great deal of debate between Member States. 

- Migration is an issue that tears apart opinion both within and between member states.

Obviously, the Commission thinks that their proposal has a chance to go through, otherwise they would not have presented it.

The fire at the Moria refugee camp recently revived the lack of a common EU policy and raised the issue on the agenda again, says David Boati.

The proposal is expected to come now on Wednesday, but nothing has been decided yet.

- We can expect a long process before we have a new common EU law in place, says David Boati.
