can a person on income support(who meets the criteria for a funeral grant) claim for help with the funeral of his father(who both have lived in scotland for over 30yrs)although the father is to be buried in cyprus?

Interesting one. The rules say that you can apply for a funeral grant for a funeral in another EU country if you are a worker, a member of the family of a worker, or a member of the family of a deceased worker (ie the person who has died), or generally you have a right of residence in EC law. That's the problem I think: all the relevant definitions are by reference to EC law instruments (directivesand council regulations and whatnot). Now Cyprus has only been a member of the EU since 1.5.2004, so whatever rights these two are and have been exercising, it is almost certainly not an EC law right but one founded in domestic British immigration law.

Your client is on IS so presumably not a worker, but the fact that he is getting it means that R2R problems don't exist. I suspect they have both had settled status. And I ahve no idea what the law woulda ctually be, but in view of the lack of EU connection for most of the period this is to say the least outside the spirit of the regualtions.
