Boris Johnson wasn't in the government - he was a back bench MP.
So nobody has reneged on anything because one organisation said one thing and another organisation will decide on these matters in two years or more time.
If Mr A said: "Lets build an airport at Dover" and the government didn't build an airport at Dover who would be reneging in your mind? The person who wasn't part of any decision making or the government who never suggested it? I don't think anybody was reneging but you appear to have a warped logic.
I think you have placed too much faith in Mr A ... man's a cnut ... we don't need an airport in Dover ffs
