I don't think there are many nicer people in politics than John Swinney. He is a very clever man, too. I wasn't aware that amongst his many talents was an absence of the need to sleep.
Thatcher was bad enough, needing only 4 or 5 hours, but Swinney will simply not have time for such luxuries as napping as he gets to grip with his massive workload.
His new ministry covers everything from enterprise to Scottish Water to e-governance to planning. Given the amount of casework one relatively small constituency generates on the latter two issues, I hardly think that one Cabinet Minister can effectively manage all of this.
Time will tell, of course. I actually suspect, though, that Swinney is the sort who would work himself into the ground through dedication and diligence. I tend to think that work-life balance is important (all around me will guffaw, I'm sure, but there are limit). You work more effectively if you have time to relax away from the office.
The other Cabinet Ministers also have full portfolios. I do hope the new Government has not saved a few quid only to compromise the health and lives of its members. The work ethic is good to a point....................
