The whole thing has been such a shambles from start to finish, from the initial campaign, to Cameron's fleeing across the horizon, to the hilarious mess of the early GE, to May's multiple other gaffs... I can't see how there's any sensible option BUT to declare the whole game "void" and revisit the question - PROPERLY and sensibly - in 5 years time. With clear and concise options with plans in place for each.
