She knows that she can call for an election all she likes - it won't happen
Calling an election at this point would be an act of intentional suicide from the Tories
so it won;t happen
The most extreme thing that may have a possible likelihood is a new leadership election
and even that would be like a slow strangulation over the next year or 2 rather than the quick fall off a cliff of an immediate election
So Dorris risk very little by calling for it but makes a point
part of that point seems to be that she is an idiot and has no intention or desire to be in the Cabinet in the near future!
