On their own merit it is clear the two front runners are BC and NS yards. After that, it gets interesting if politics is involved (which the government swears won't happen, but I will reserve judgement). There certainly won't be an appetite to give it to the QC yard, since the Tories certainly got stung there in the last election. If anything, the power shift to the west may favour the BC yard if politics becomes an issue.
If it is merit based I think that NS has an ever so slight edge over BC, but just.
It will certainly be one of the more interesting decisions to come out of this government in the next while.
