This has done the opposite though, where even the former Labour MPs won't vote no confidenceThe Labour party, sure. Emptying the Conservative party of a few might actually be a good thing, though, because it frees those MPs up from the whole party-over-country thing (or at least changes them over to a slightly more sane party), allowing them to vote against their former party more easily - and if it comes to it, that includes a vote of no confidence.
