There are two elements to public service whether elective or by appointment:
1. To DO the right thing
2. To be SEEN to do the right thing.
The second element is widely disregarded . . . assuming that public servants (politicians in particular) are even aware of it! Had MPs (and Lords) kept this second element at the forefront of their minds, instead of assuming that they would never be exposed, much of the recent (and ongoing) expenses scandal would not have occurred which serves to emphasize how low current standards of conduct are!
From an English position, the latest farce is the spectacle of a Scot, Danny Alexander, making commitments for England. It might have appeared a tad better had the Chancellor of the Exchequer himself made the announcement that the British Government (ie the English) underwrite all of Scotland’s share of the British state debt even if Scotland votes to go independent, but then, Gideon Osborne is only a Brit!
