People need to get to terms with the fact that we've finally caught up with much of Europe (and elsewhere), and no-longer have a system of binary majorities, despite having a FPTP system that is gamed to favour this. Its annoying that people (goaded by the right-wing press) believe that there has to be a "winner", and this "winner" has to form parliament, or its not legitimate.
The conceit of both, including Labour, demonstrates this. Refuse to even contemplate deals in the run up, and claim that only a majority works. The best line I heard last time (Andy GI off 'ere), was that it would be pretty interesting if the smaller parties had a manifesto stating what they would attempt to do in a coalition, where red lines were, priority and secondary policies. This would at least be hones). It'd make, say the greens for example, more believable, than the current "A green government will" line.
I would imagine that a further election would erode both of the major parties positions yet further.
