The French not only support this but they have been proposing it as part of the solution for a few years. They have no problem with processing centres staffed by UK officials, it is UK officials on French beaches or patrolling their waters they take umbrage at.

I see earlier that you now see the best remaining solution as the UK following Russia and Belarus by exiting the Council of Europe meaning we could start removing aspects of the European Convention of Human Rights that we didn't like.
I had thought that the current government started to try and implement this with its Bill of Rights replacing the Human Rights Act that enshrines the ECHR before they pulled the plug on it about 6 weeks ago. The ECHR is interwoven into the Good Friday Agreement and the Withdrawal Agreement with the EU.
I know it is flavour of the month for a cabal of right wing Tories and populists like Anderson but it would be interesting to understand why you think the pros of such a move outweigh the cons?
