Likewise, nobody will be all that surprised, or disappointed, if Binface never takes his seat. It's much more of a protest vote than voting Sinn Féin in Northern Ireland, and voters will have achieved their aim of Farage not getting in.

Actually, I'd take issue with describing Sinn Féin as a protest vote at all. They've historically been the only choice that even claim to represent constituents in many areas. And they do seem to do much of the work of an MP (writing letters on behalf of constituents, lobbying government agencies...) they just don't vote or debate.
