A relative has essentially been living off grid- he was homeless for a while and doesn’t have his expired passport. Estranged from immediate family.He was banned from driving decades ago - He has no ID documents bar benefits correspondence. He lives in a HMO and now wants a passport. He is isolated socially bar me. I would like to help him at least get a new passport but I doubt if I could vouch for him as I’m not independent. His GP surgery won’t do passport ID forms//certification and he says his Jobcentre don’t get involved. What can he do? I would vouch for him as I have known him my all my life ( no risk to me). He has no friends bar acquaintances in the pub . Grateful for suggestions please.
