- Lavery didn't stand, despite some membership and union support (and being named by 'sources on the left' to the Morning Star as one of the most likely), and instead supported Andy Burnham. The NUM payment would be an issue and, as the incident with his son shows, within the left he comes from a very different place to Corbyn. Because of that, he would be nowhere near as unpopular with the people Corbyn was unpopular with; though equally it should be mentioned that he wouldn't have the same appeal (however limited) Corbyn did.
- Mearns would be even more of a "who?" than Corbyn, and ended up nominating Yvette Cooper of all people. That in mind, he's the MP for Gateshead and part of the 2010 intake. There's little to say about the man except that, as a committee chair, he didn't have a shadow portfolio or (again) any sort of profile during the Corbyn leadership. Like Lavery, he's not really from the same background as Corbyn is. He was apparently part of Militant at one point. Perhaps what should be mentioned are the comments of one Ivan Lewis: "somebody of great integrity who is genuinely committed to fighting antisemitism."
- Trickett didn't stand because, having been a frontbencher, he had left the Socialist Campaign Group and was concerned that he wouldn't have the left's full support. Let's say that Lansman manages to succeed in persuading him in their meeting, he gets the nominations required, and from there wins the leadership as in hindsight it seems that any candidate of the left would have. He was close to Miliband and would have been more within the party mainstream than Corbyn was or, say, McDonnell or Abbott would be, but his leadership would still mean a significant shift to the left.
