President Kaunda made Zambia a one party country in 1972. He was the leader of the UNIP. There were two other political parties at that time and they resented not having a voice. In 1991, there was enough of resentment that Kaunda allowed a return to a multiparty system. Chiluba was elected in 1991.
Though parlimentary governments differ from country to country, they function in more or less the same way. As the distinguished Canadian parliamentarian Stanley Knowles put it: ... the opposition should so conduct itself in Parliament as to persuade the people of the country that it could be an improvement on the government of the day. No one will deny that our system works best when there is a change of government at reasonable intervals. The role of an opposition party, Mr. Knowles noted, is to check and prod, but ultimately to replace the government party. http://fergionline.blogspot.com
