AstraZeneca | Sizes of cities | Starlings | Mickey Mouse degrees | Passport photos
As a participant in the Oxford University Covid-19 vaccine trial, I’d be put out if AstraZeneca rushed through a deal with Donald Trump in time for the US presidential election (Oxford University Covid-19 vaccine firm says it is not in talks with Trump, 24 August). AstraZeneca must issue a less ambiguous rebuttal of the reports of such a deal. If it doesn’t, I’ll withdraw from the trial.
• Britain’s most populous city in its own right is in fact Birmingham (Letters, 24 August). While Greater London is Britain’s biggest urban area, only the City of London and Westminster have city status. Manchester comes fourth (after Leeds and Sheffield), though this may depend on which boroughs you include – not Salford, surely?
