May urged to suspend any Tory MP that refuses to back her deal,
Her majority is so incredibly slim - it's basically a minority in fact, at least w.r.t. Brexit - that I can't see this being a credible threat. Unless she's planning a GE very soon (not unreasonable)

23.18 update most interesting:
May urged to suspend any Tory MP that refuses to back her deal,
flushng them out, as they then could not stand in any election as a Conservative.
The break up of the Tory party is the logical conclusion of the nearly 30 year internecine squabble that resulted in the Referendum.
I doubt May has the fortitude to carry out this suggestion of suspension.
