A trade union representative describes a phone call that they have received from a senior officer of a public body. She describes content to her member. The e mail names the senior officer making the phone call and describes an improper offer - essential to improve a reference if the party withdraws a professional complaint.
The originator of the trigger call has tried to "advise" that release of this e mail would be in Breach of Data Protection Act - his misdemeanours would be exposed.
Obviously there is a public interest as well.
