The government has just changed the Immigration rules again, to make clearer certain important elements to the rules.
Refugee status will be withdrawn if someone obtained that status by deception. It will be withdrawn if the protection is no longer needed. It will be withdrawn if the person commits a serious crime, or becomes a threat to our national security.
New rules highlight the fact that no national arriving from the EU can make an asylum claim. Under EU law all EU countries are deemed to be safe, so any claim for asylum should be inadmissible unless there are exceptional circumstances. In future the UK will normally regard any EU national claim as inadmissible. If they present a case that they are exceptional it will be considered but there will be no right of appeal against a decision.
These and other changes are to tighten controls under existing EU rules, and may be helpful at the margin. Clearly they cannot and do not deal with the bigger issue of freedom of movement.
