"Young, I thought that Con had the right to have a minority leadership?"
He has a right to TRY - but if they can't get a Queen's Speech voted through parliament then it won't work. And clearly if there was a lib-lab pact then they would never get a Queen's Speech through.
I think if they failed to get a Queen's Speech voted through it would automatically trigger a vote of no confidence (which again, as a minority facing a lib-lab pact, they would lose) and that automatically triggers a general election.
So yes - he could try to have a minority gvt, but not in the face of a lib-lab pact.
