Among the groups taking part are Fixing' T&T, the Joint Trade Union Movement (JTUM) led by Ancel Roget, David Abdullah's Movement for Social Justice (MSJ) and the Federation of Independent Trade Unions and NGOs (FITUN).
The national Union of Government and Federated Workers (NUGFW) is not participating in the anti-government event.
Its leader, James Lambert, is a government senator and a member of the United National Congress (UNC). Lambert is staying out because he feels that the march is too politically focused.
The PNM is sponsoring the march, which it says is to highlight the failure of the present government.
The government isn't bothered about the event. It has said its policies are sound and its support remains constant.
The march is a serious event, but one cartoon circulating on the Internet has put an interesting spin on it, suggesting that the PNM and its leader are leading followers astray. The cartoon is reproduced below.
