Some idle musings I placed on another forum..
Don't take them too literally.
"As I understand it, it would take a lot of Tories plus the combined opposition parties to outvote the Govt. Whilst there's little doubt that many Tory MPs are very dissatisfied with the Govt, many also know that an election any time soon would see them out of a job, and the Tories out of office for a very long time. Given the scale of the Tory disaster, it's even possible the Tories could be wiped out in the way the Liberals were early in the 20thC.
I'm not entirely sure how a particular vote becomes a 'Vote of Confidence'...I'll have to check on that.
Also, the circumstances now are different to those prevailing in the early 20th C . Back then Labour was rapidly gaining a foothold in the consciousness of the working population, offering something fairer than the class ridden social structure and inflexible certainties of the Victorian and Edwardian periods. WW1 certainly hastened that process.
So, put simply, Labour replaced the Liberals as the 'progressive' force in UK politics.
At present, there's no cohesive ideology waiting in the wings to replace the Tories, so even if wiped out in the short term, they'll no doubt blunder on, picking over what's left of the UK that they can steal, sell off, etc.
Labour is no longer able to offer a way out of the class system etc. as that has all but gone, so the offer at present is essentially a 'nicer' form of Capitalism. Labour need to find a much more targeted and cohesive alternative to the Tories. Winning on the basis that they are the 'best of a bad bunch' isn't sustainable. That said Labour are rightly wary of pronouncing too many definitive policies and spending commitments because, despite all evidence, people, egged on by a rabid foreign owned right wing press, are still easily convinced that Labour is a 'Tax and Spend' party, so any slight error of judgement will be pounced upon by the press.
If the Tories do a 'Liberal Decline'..their replacement needs to come from some sort of coalition of Green/Environmental/Lib Dem etc. groups.
...maybe.. "
