Books on why French women don’t get fat and the beautiful behaviour of French children have reinforced the image. Now the Sorbonne, one of the world’s most elite universities, is inviting Britons to France to be lectured about the virtues of being French. Aimed at expats, students and retired couples, the summer course will be taught in English and French, to appeal to Francophiles across the Channel.
