You're right Maw. Ooops! I was obviously tired (my excuse anyway). It was probably one of my dud edits, when I change the sentence round,but confuse myself. Doh!
There's no way that Corbyn will be PM, so I don't think anybody needs worry about that. It concerns me far more that the Conservatives have a huge majority and won't be challenged on anything - Brexit related or otherwise. At least one prediction is that the Conservatives will win at least 10 seats in Scotland.
Ukip is practically dead and there's evidence that Ukip supporters are now supporting the Conservatives, so May can't become too soft. Most of them came from the Cons in the first place, but some formerly voted Labour. That's one of the reasons the Cons are now polling so high. The Conservatives are losing some of their more centrist supporters to the LibDems, especially the ones who voted Remain.
Miller's aim is to keep the Conservative majority low.
