Who are the donors?

WHERE is the anti-Lisbon Treaty group Libertas getting all the money?

Recently I noticed an advertisement on one of the boards in Kent Station, Cork. Although, I am pro-treaty, I have no problem with people voicing and showing their opposition. But what concerns me is where is Libertas getting the money to do such things?

These billboards come at great cost. Libertas is a small group made up almost entirely of wealthy businessmen. They should release records of all campaign donations and expenditure. It is a matter of public importance.
