Not Duncin’ but I answered this up the thread.
To note asylum claims are accepted or rejected, rather than refused. Those rejected may be able to exercise a right of appeal at a tribunal. On some of the appeals the Home Office will withdraw the rejection pre-court and reconsider. Some are court ordered to be reconsidered. Some rejections are overturned at court and some upheld. The numbers of accepted claims via court process increase considerably the number of overall acceptances tbh.
If the Ho were considering claims incorrectly to allow people in then they’re not doing a very good job are they as the tribunal has to correct a considerable number of rejections at that point.
There is an 80k tribunal backlog so some claimants initially rejected are still classed as asylum seekers and allowed to stay pending appeal, as per our processes and in line with our legal system.
Where appeal rights are not utilised in a set timeframe, or appeal rights are exhausted then the claim is fully rejected and there is no right to remain. At that point all accommodation and support is withdrawn and the claimant told to leave. Some will return or leave voluntarily, some will be returned (not removed as that applies to court sanctioned leaving). The numbers being returned overall have gone up.
If any stay they are not doing so on the government’s money. It is really probably easier to return failed asylum seekers than others as there is easier access to them - being in a specific place.
There are definitely not 1000s of failed asylum seekers roaming around illegally seeking B&B on the black economy. Illegal immigrants are actually more likely to have arrived as visitors or on another route and overstayed. But of course no illegal migrant can access any housing, welfare, legal work, NHS beyond angel care etc so they’re not draining our resources in that sense - the ones most commonly mentioned.
