The Lib Dems won't be enough on their own to put this into play. It would need the 21 former Tories to back it. It would need Labour Brexiters like Kate Hoey to back it. It would need those who explicitly left the Labour party because of Corbyn to back it.
Everyone except Corbynites know how unpopular he is, and it's sad that they can't see that they're just the opposing wing of the Eurosceptic loons who think the sun shines out of Johnson.
It's true that I singled out the Liberal Democrats unfairly (mostly because their hypocrisy in professing to oppose Brexit at any cost is easily the most egregious).
But you're still applying the same spurious logic I described earlier.
Pretending that Corbyn can't be trusted as a strictly nominal PM in a temporary caretaker government is transparent rubbish, because no matter how unpopular or extreme he may be, the other coalition members can (and would) depose him should he so much as wink at executive action, save secuing the extension and the election.
The only possible objection to observing hundreds of years of protocol (and the
actual objection of the Liberal Democrats and the rest of the heap, many of whom have already fled their constituencies to escape certain defeat to Labour) is that Corbyn will probably secure the extension and the election quite capably, and look compotent and authoritative on television while he's at it.
And the fact that your Liberals (and, yes, the rest of them) won't risk even a fortnite of Corbyn's face above the 'Prime Minister' caption each night on the news suggests they know his prospects with the public are actually far stronger than you'd prefer.
