The Directors of BPH (from the website) are:
Mr David Breeze, Chairman
Mr Tony Huston, Non-Executive Director
Mr Charles Maling, Non-Executive Director

and the Directors of Advent (again from the website) are:
Mr David Breeze, Non-Executive Director
Mr Stephen Kelemen, Non-Executive Director
Mr Tony Huston, Non-Executive Director
Mr Thomas Fontaine, Non-Executive Director
Mr Steve James, Director

David Breeze is also a director of:
Cortical Dynamics Limited,
Molecular Discovery Systems Limited,
Diagnostic Array Systems Limited,
and Advent subsidiaries Asset Energy Pty Limited and Offshore Energy Pty Limited.

So you can see it is firmly controlled by David Breeze and his associates. David is on the Board of both companies as is Tony Huston.

So while MMR holds 53% of Advent, it is just a shareholder like anyone else. It has no control of the day to day running of Advent.
