It’s a spectacularly poorly worded graphic, but in case you’re wondering, it’s about alleged abuse of modern slavery protections to artificially delay deportation, not a threat to enslave people:
The phrase "Secure beneath the watchful eyes" really reminds of the Techno-utopian poem "All watched over by machines of loving grace", it has the same bold wrong-headed naive optimism in a higher power able to keep us safe, like a security blanket.
"Modern slavery system" is hilarious, but even more worrying is claim that one might ever lose the modern society's protrection against being enslaved under some conditions.

“If you come to the UK illegally you will be DENIED access to the UK’s modern slavery system”
Put that in a 70s typeface and slightly weathered poster appearance and it’s pure Scarfolk.
