The Unity Trust Bank seems
The Unity Trust Bank seems better, but it has close links with the Co-op Bank which provided the initial capital and still has a 26.66% share in it. We used to bank with the old Girobank, as a state as opposed to a private bank, but this got privatised in 1989 and is now owned by Santander. Maybe the new Post Office Bank to be set up next year (it's only Royal Mail not the Post Office that has been privatised), which is a sort of attempt to revive the Girobank, could also be suitable.
