Permanent residency in Spain based on previous right of permanent residence in another state.
Came across the subject in the title on another forum which suggests that it may be possible to exchange the right of permanent residency in one EU state for the same in Spain via a form here
My Spanish is not yet up to reading such a document and translations are only of limited and dubious accuracy so I wonder if anybody else has any information on this or at least can faithfully read the document and advise if it does mean what it's claimed to.
From the other forum on the face of it the principal difference would seems to be that the
Spanish Residencia de larga duración-UE is awarded to NON EU citizens, a
status which of course will apply to British citizens following a no
deal Brexit, so it would seem perverse in the extreme to discriminate against and deny a former EU citizen forcibly stripped of that status by the madness of Brexit.
For background before coming to Spain we lived in France for 11 years and although at the time we'd already pretty much made the decision to relocate we nevertheless in 2017 obtained permanent residency via a Titre de Sejour (residence permit) which states on it's face "Sejour (literally 'stay') Permanent" and bears no date of expiry.
We obtained our Spanish residencias last year so have some way to go for permanent residency so the exchange suggested could be of significant benefit, especially if it endows freedom of movement.
I will certainly be looking further into this.
