interesting thing happened to me 2 years ago.
i changed my car--bought an MG--notified insurance brokers--who said my insurers wouldnt cover it---so i had to cancel policy and buy a new one with a different company. which i did.
new company required me to send in photocopies of my driving licence---which i did--plus also my (then ) wifes licence too--as she was a named driver.
she was "unable " to find her licence.
next week--she left me-----------
