How could Churchill"s government have plausibly unseated as a result of the great smog, without the cause being Churchill's health being significantly damaged by it? How long would it have to continue, and how much would he have to bungle the reaction to it to lose the Prime Minister-ship?
Queen Elizabeth II was contemplating asking Churchill for his resignation, over his "mishandling" of the Smog.
You could also see the by-elections in some London constituencies such as:
- Bromley, who was held by Harold Macmillan (Conservative)
- Battersea South, who was held by Ernest Partridge (Conservative)
- Lewisham West, who was held by Henry Price (Conservative)
- Woolwich West, who was held by William Steward (Conservative)
With these loses, and Churchill's resignation, who ever succeeds him [most likely Sir Anthony Eden, as Secretary of State for Foreign Affairs and Deputy head of government] may face a vote of no confidence and see a new election.
