David I believe that you are wrong about India.
Turkey and Jamaica do have some particular challenges:
Under the framework established by the Illegal Migration Act, India is officially listed as a "Safe State" (Section 80AA) list. Maybe you missed this as I believe this was in 2023.
You are right that Jamaica is not on this list though it used to be. It was actively removed in 2015.
So, we don't operate fast-track removal to Jamaica or declare asylum claims automatically invalid.
We can and do still return or deport someone to Jamaica if they have no legal right to stay in the UK (like an overstayed visitor or someone who has committed a crime), but if that person submits an asylum or human rights claim, the Home Office cannot just ignore it.
Jamaicans are given a review.
Most reviews are on the basis of sexuality. I don't think this is unreasonable because of the well documented appalling treatment of LGBTQ+ people there.
Turkey is not on the statutory "safe" list either, but the UK actively and aggressively returns people there through a fast-track agreement.
However, political dissidents/activists and people vocal about Kurdish rights are in danger in Turkey.
Economic migrants are handled as routine returns but if they are on the radar of the Turkish state or police for political or ethnic reasons, UK courts treat Turkey as unsafe and will block the deportation.
So although David you are right technically about Turkey and Jamaica - we can and do still return people there - but not without looking at their actual situation first.
