Balpa dont have a president.
You are confusing Balpa head office with the 'local' KLCuk Balpa team.
VNV refused all 'round the table' talks with KLM/KLC Balpa and VNV dating right back to the time when KLMuk were been 'combined' with KLC. To this date, as far as I am aware, VNV have refused to talk with management and Balpa together despite many requests from Balpa. If they had have done in the first place all of this may have not happened.
What you are talking about is the time when the Balpa delegate became the president of ECA and the VNV representative did not. It was won on a full open ballot within the ECA member associations.
Shame on anyone to suggest bad mouthing, I am sure all the elected members of the ECA who had the authority to vote would not take into account anything such as you suggest. They are professionals.
