John Allen Fraser Quote

As our parliamentary system now stands, we say that this role of overseeing the Government has probably become the main function of the House of Commons. the purpose of this function is to illuminate the weaknesses in government policies, the errors that may have been committed and the sectors that may have been forgotten, and to suggest alternative solutions.
