I had a somewhat vigorous disagreement with my wife over dealing with the middle lane hog on an otherwise quiet motorway. We were on the M1 near Sheffield at the time and my wife was driving doing 70ish. The road was clear for some distance in both directions when we approached a middle lane hog doing 60ish. My wife passed him on the left and when I pointed out she should have moved out and passed on the other side I was told in no uncertain terms I was wrong and she was right. I have since checked the Highway Code and, although my interpretation is that you should move out and pass on the right, we still disagree over this issue.

Even worse is the right hand lane hog on a two lane motorway. I have more than once followed a car doing 55 - 60 in the right hand lane on the A19 when the left hand lane was clear for some considerable distance ahead.

The highway code is quite clear about joining motorways. You should give way to traffic already on the motorway.
