Similarly for months every time I come to r/ukpolitics the UK prime minister is on the verge of being ousted

To be fair the latest event wasn't in discord with the rest of the UK media.

Multiple sources were under the impression the ERG were trying to push for a vote for no confidence... because they were. That was a legit concern before Brady came out and called them out on it.

As for the current event the DUP really are going back on their agreement( they claim May went back on it first ) and this is a very real threat to May arguably far more than the ERG.

Not sure why you think this is hyperbole these are real threats and the reason they seem to popping up all the time is because they all relate to Brexit coming to head.
