There isn't any legal route for your "illegal immigrants". There are, from time to time, temporary country specific routes (E.g. Ukraine, Afghanistan, Hong Kong, etc). There are other schemes, such as the Family Reunion scheme but we've discussed in depth the arduous, difficult and dangerous travelling concerned in that process.You really are The Humanitarian, aren't you.
Let's seperate the legal migrants from the illegal immigrants for a moment and try to avoid conflating the two,,.
What 'safe and legal' routes do you suggest the govt. provides for illegal immigrants; other than the ones already in place for legal traffic, that is.
I've already suggested a fortnightly ferry. That will easily accommodate the annual flow of the channel crossings.
Because the ferry would not be considered a rescue ship (in the terms of SOLAS), the ferry would also serve as temporary refugee accommodation, and the asylum process could begin immediately.
Two weeks is considered far too long for immediate refugee accommodation for immediate processing centres. So onward re-accommodation would be completed well before the next departure.
The ferry service would immediately disrupt the criminals market, allow SAR service to return to their core service, and release the money given to the French
And most importantly, provide a safe and legal route.
