"...but otherwise this vote will have resulted and be the sole responsibility of the Tory rebels."
Somewhat off-topic, but why is it that when a group of people take advantage of a procedure available to them to see a change they want made, it is seen as "rebellion". The Conservative party has a mechanism to challenge its leader via a VONC. Some MPs want to invoke this process to remove a leader in whom they have lost confidence. Why, then, are they "rebels"? Surely they are people with a particular point of view and want that view tested in a wider audience.
