I learn something every day.
When I did my RT licence and ATCO training (many years ago)
the phaseology was "PAN PAN PAN (Station Called) this is (Callsign) PAN PAN PAN"
The phaseology from CAP413 (Radio Telephony Manual is:
1.2
States of Emergency
1.2.1 The states of emergency are classified as follows:
a)
Distress A condition of being threatened by serious and/or imminent danger and
of requiring immediate assistance.
