The rules are very fuzzy, and I think you have to actually work on those days, as opposed to simply being there on holiday or visiting family friends.

But they've also talked about clamping down on people who send their dependents back for long stints, own residential property that they then claim as a child's residence for the purpose of university fees or other benefits.
