I see from the Electoral Commission web site that the veterans card is not listed as one of the government issued photo IDs acceptable for proof of identity when voting.
I can beat that! Nearing retirement I had applied for a Civil Service job in an RAF Command HQ where I was then working, was shortlisted and duly interviewed by a serving 2-star.
His (civilian) outer office was checking my identity - and I discovered that my 1250/Mod90 was
NOT acceptable ID!!!
Fortunately I was about to go on hols so had my passport in my bag .......
[Didn't get the job ...... maybe cos I told the AVM what I thought of the above]
