So,
Following several conversations re: FILs memory and his ability to continue driving, I’m still no further forward...
I’m now at the point where I’m seriously considering an anonymous referral to adult social care in the hope that they will recognise that MIL is continuing to ignore his current memory issues and covering her entitlement to be driven everywhere and taken on holiday several times a year!
Also, I’m told the only thing they can do is give a courtesy call to check if they require any help, is there anyone else I can approach to get FIL the help he needs?
