I don't know how many times I have to point this out before you get it, but this isn't actually true.

If for whatever reason the Conservatives cannot get a Queen's Speech passed, or lose a vote of no confidence, then as the leader of the opposition Jeremy Corbyn is invited to attempt to form a government. In such a situation, all he would need is for the Tories to abstain on crucial votes to get legislation passed...and if they didn't, they'd be staring another election in the face which none of them want. In theory, one MP can govern alone so long as every other MP doesn't vote against them. Which is also why the Tories don't absolutely need to depend on a deal with the DUP, they already have more MPs than all the left-of-centre parties put together, and could govern as a minority so long as there weren't many rebels.

Is this likely? No. But is it impossible? No. All it would take is for a handful of rebel Tories to not vote through supply and confidence motions, and they fall.
