That is not what the Home Office is looking for, Corby. And in any case, why should they? This scandal is slaughtering businesses and towns. Any hotel that accepts these contracts are unlikely ever to resume proper business again. That may suit them - especially if they are not particularly successful. But an influx of mainly young males, roaming round a town with nothing particularly to do will very soon ensure other businesses in the town suffer as well.
We should not be looking at ways to accommodate these people. We should be looking to (preferably) keep them out or at least return them whence they came. Yes, I know it's difficult (at least the government makes it so by their continued acquiescence to agreements which do not suit us). But that's why we have a government to solve these difficult problems rather than simply shrug their shoulders.
