In common with blogs of all political persuasions, advertising on my blog is handled by MessageSpace. They ask advertisers which blogs they wish to appear on and the adverts are fed through. I can veto any advert if I want to, but if I did I would no doubt be accused of censorship. Accepting an advert does not imply my endorsement of the product or campaign whatsoever.
I have a living to earn to keep
So let me be clear. I support Boris Johnson for Mayor of London (come on Boris, when are we getting an ad from your campaign?!) and I support the building of a third runway at Heathrow. Clear?
