I'm no expert on politics but according to Ladbrokes who obviously do employ savvy analysts the odds on a Labour Coalition made up of them plus either/and the LD and SNP is 33/1.Not sure it is, if the tories don’t have an overall majority then unless they are close enough to get a majority with DUP support it will be impossible to form a government and Labour plus Liberal / SNP would be more likely. Think the tories would need to win a majority or be within 10 seats of one to govern. Especially if we have a deal and Farage goes after them.
So even if we get a withdrawal agreement by 31st and move to transition the new deal could look very different depending on who’s negotiating it.
Bookmakers do make the wrong call now and again but those odds convince me more than your opinion, not belittling your POV, just using head over heart analysis.
