Its interesting as they said he didn’t proprogue correctly and its null and void but NOT that he couldn’t do it.
I’d bet he will wait a few days and then do it all over again with clearer justification and suggest that if they don’t like it, they have a recourse which is to call a vote of no-confidence, which of course they don’t want to do.
Interesting gamesmanship - trying to force someone to resign, and take over parliament without an election, but without using the specific mechanism in law to do it. The fact is that the opposition can do nothing except call an election as that’s the only way to change a government - you can’t call shotgun and grab the front row the house and claim you bagsied it (even though it would be highly amusing to atch them try it).
And the date gets ever closer …
