Struan Coupar, of Bowden, Dartmouth, writes:

Your correspondent Keith Williams, whose letter you ­published at considerable length, Chronicle, June 17, had nothing to contribute other than a repetition of the many points argued in favour of Brexit in recent weeks by Messrs Farage, Johnson, Gove et al.

By contrast, your other correspondents on the same subject offered personal opinions from individual perspectives and contributed something positive to the debate.
