It has been suggested that we need a "British values oath" for public servants.
Can I suggest we just make them sing the first verse of "I Vow to Thee, My Country"?
Its exaltation of one's country above all other earthly things - human love, truth, justice, freedom, for instance - seem to fit into the modern populist patriotism quite well. Why would you need any of those when you've got British Values? Which should mean democracy, sense of humour and self-deprecation. But these days probably means hatred of foreigners and a general sense of grievance.
