[UK-CONTEST] Remote Operation

[Cooper, Stewart]

Slightly off topic for which I apologise, but there is a wealth of knowledge on here! If one operates a station remotely what callsign should be used? I can operate my home station using a remote connection over the internet. If I'm in GM then I would sign GM4AFF anyway. But if I let my QSL manager Linda M0CMK operate it remotely, what call does she use - M0CMK or MM0CMK? This could get a lot more complicated, if I was in Holland and operated remotely, what then?
