In a recent post I accidentally left the name of my correspondent attached to the question that was posed. For this I offer an unreserved apology. It is my practice to always maintain the confidence of my correspondent’s identity. Of course I cannot help it if people ‘in the know’ can infer who a correspondent is but it is my practice to always remove, and keep confidential, identifying information. On this occasion that did not happen.

The post has been deleted and to that person again I offer my apology. To future correspondents I confirm that it is my intention to continue to keep confidential the names of people who write to me.
