By claiming protesters against a low traffic neighbourhood in Oxford are somehow part of a QAnon conspiracy, Siddharth Venkataramakrishnan seems to be borrowing one of London mayor Sadiq Khan’s habits of casting all opposition to his plans for extending ultra-low emissions zones as belonging to an anti-science rightwing confederacy (“How the 15-minute city became part of the ‘everything conspiracy’”, Opinion, House & Home, March 11).

All protest movements attract extremist fellow travellers. But in my part of London at least, there are concerns from those of all political persuasions. LTNs were implemented so rapidly, without basic data collection, that it is very difficult to persuade locals they have done anything more than shift traffic from one street to another, increasing congestion and thereby pollution.

Could you also reassure your correspondent that he should not be concerned about protesters trying to gain council seats. That’s rather how democracy is supposed to work.
