There is no opposition in this round because it is a total farce initiated by Farage. It takes two to tango and no one else (other than Count Binface) is dancing Farage's Doofus Dance.

If Farage wins, he will face the inquiry he is attempting to escape by pulling this stunt (in a summer where the WC is happening, Farage managed to score the biggest and most protracted own-goal in the history of own-goals). An effect of the inquiry is that it will trigger _another_ election in which the other parties are expected to field a candidate.

I'm not from the UK so I don't know the proper terms/political procedure but if you read up on the whole situation beyond the jokes, what I said above is a good rough outline. This is hardly the death of opposition to populists.
