However useless the Tories may be, their hands are tied. The left constantly block attempts to deport illegal immigrants, or people who've overstayed their student visas, etc
The Tories have been in power for 13 years. Despite the fact that their current majority is ever-shrinking, they still have a fat overall majority. How on earth do you claim that the left are blocking them from doing anything effective about illegal immigration?
If, as I suspect, you are talking about judicial reviews preventing individual deportations, there is nothing left-wing about this. A judicial review can ONLY succeed if the claimants can demonstrate convincingly that the action in question is unlawful or wholly irrational. If the Home Office complies with the law in deportation decisions, judicial review applications won't succeed. In any event, deportations stopped by JR are in very low figures and barely touch the surface of the immigration issue.
The truth is, as the government well knows, is that they could deal much more effectively with illegal immigration by having an efficient asylum processing system to weed out unmerited claims, and an efficient policing and immigration control system to find and deport genuinely illegal immigrants. They haven't chosen to use those solutions, mostly because the likes of Braverman are much more interested in posturing in Rwanda, which is another so-called "solution" that will achieve nothing.
In the meantime, they keep rather quiet about legal immigration numbers because their supporters wouldn't like it and they do rather give the lie to claims that we have no room for immigrants.
