Emmanuel Macron | Butterfly Conservation | Country diary magic | Porton Down | Football fansWhy is Emmanuel Macron always described as a “centrist” in the Guardian (Strike chaos sets rail workers on collision course with Macron, 4 April)? He is hellbent on reducing employment rights and taking on the unions. He may be young and his party new on the political scene, but he is a conservative. Why not describe him as such?
