I don't understand your logic there. I'm just speculating that we want our government (whomever it was) to be able to concentrate on the Brexit deal, and not have to worry about the opposition or lack of mandate etc. If Labour were united and well lead now, they could put pressure on May to call an election, which is not what we need right now. As it is, we know May would win if there was an election, so there's no need for them to do it.Why special conditions in this post-Brexit scenario? It's almost as if you're conceding that it constitutes a major error.
