As a British Francophile, and former student at Nice university, the call from Foreign Secretary Johnson for an ever closer union of our countries (Report, 14 July) shocked me by the bitter irony of his having destroyed that at EU level. It is heartbreaking that our governments, which should be focusing on defending us all from our ever-present enemies, are forced instead to waste enormous energies on all this Brexit madness, which so divides us, and which Johnson himself has inflicted on us.

• The dreadful news from France reinforces why we should stay together and work for a strong, equal and united Europe. Liberty, equality, fraternity and peace in Europe today… and maybe tomorrow in the world.
