I strongly support the principle of family unity, but it is important to note that there are already legal routes for families to be reunited safely that are not dependent on our EU membership.
The UK's family reunion policy is generous, granting over 23,000 family reunion visas over the last five years, and I can assure you that the Government will continue to reunite refugees with their immediate family. The EU Dublin Regulation determines the Member State with responsibility for assessing an asylum claim.
Under the Regulation unaccompanied children present in another EU Member State can be transferred to the UK to have their asylum claim assessed where they have a qualifying family member or relative legally present and transfer is in their best interests. I do expect cooperation on asylum and migration with our European partners to continue after the UK leaves the EU, and will follow this topic with interest as the exact nature of this cooperation becomes clear during the negotiations.
