No, there are no competing debates commissions. We've had ventures. There was a group at the University of the West Indies who tried to do a debate. They did not get very far toward even organizing it. They certainly never got to the point of calling the politicians. Then there was another youth group who tried also but again did not get very far.
Really since the entire talk about having debates, the Trinidad and Tobago Debates Commission is the only one that has been consistently calling for the debates.
