Conservative leadership election

[Okay, maybe Mike Johnson is a competent parliamentarian.]

Two questions:

1. If May is out on June 6 and the leadership contest goes into mid-to-late July, who'll be PM in the early summer months? Will May stay on as a caretaker or will there be some sort of interim PM? If the latter, is there any precedent for that? I know there hasn't been in the past century or so, but perhaps something from the era of revolving-door Georgian/early Victorian PMs?
2. I suppose Rory Stewart has no chance? He's the only one of these people I sort of respect.

Does an MP need a certain number of backers to be an official candidate? Also, can an MP endorse more than one person? Wiki list David Davies as having endorsed two people.

I seem to remember reading that an MP needs to be backed by at least two others, but I can't remember where I read it.

Is it significant at all that Raab only has the support (so far) of three MPs from north of Birmingham (and none from north of York), while BoJo, Hunt, and Gove all seem to have much more support in Scotland and the North?

Wikipedia says David Gauke (South West Hertfordshire, current Lord Chancellor/Justice Secretary) is backing Stewart.
