I am wanting to lend my car to a friend for a few days later this year. The issue is that he is now a Canadian citizen, and holds a current Canadian driving license. He tells me that he could get an international driving license fairly quickly if that would help. He is originally from the UK, learnt to drive here, and had a UK license which he never sent back to the DVLA, although he has lost it and obviously the address would be wrong. I suspect that UK license would be invalid now anyway? Do you know of any way in which I would be able to insure him on my UK car for a fortnight or so (in June this year)? My current insurer won't, and from my initial searches on the Internet that seems typical. Any suggestions would be much appreciated. I have read somewhere that Hertinsurance.com might, although their website mentions nothing about it.
