LIS I am pretty certain that is actually less than a month (30 days) you can be in the UK now in any one year. It changed about a year and a half ago. I have a feeling it may only be two weeks but I can't be sure. It didn't affect me so I din't pay much attention. But they are really clamping down on what they class as tax dodgers. Anyway like I say I am not certain, and can't be arsed to look it up, but to anyone that this could affect I would recommend checking.
