I took part in this poll (as a Conservative Party member). The fieldwork was conducted 30 June onwards, so represents a situation before Boris Johnson had resigned.

Wallace wouldn't be the worst candidate out of the current runners. My sense is that the Conservative Party as a whole has zero appetite to go back to lockdown and business closures, and views the whole episode as a mistake. However, most MPs still brag about having delivered the vaccines "first" and faster than Europe, so the ineffectiveness of the vaccinations hasn't sunk in with them yet.

If they bring back anything it's likely to be masking, to be honest.
