The constitutional changes came into effect on 1 January 1988 with Robert Mugabe as President . The bicameral Parliament of Zimbabwe had a directly elected House of Assembly and an indirectly elected Senate, partly made up of tribal chiefs . The Constitution established two separate voters rolls, one for the black majority, who had 80% of the seats in Parliament, and the other for whites and other ethnic minorities, such as Coloureds, people of mixed race, and Asians, who held 20% . The government amended the Constitution in 1986, eliminating the voter rolls and replacing the white seats with seats filled by nominated members . Many white MPs joined ZANU which then reappointed them . In 1990 the government abolished the Senate and increased the House of Assembly's membership to include members nominated by the President . </P> <P> Prime Minister Mugabe kept Peter Walls, the head of the army, in his government and put him in charge of integrating the Zimbabwe People's Revolutionary Army (ZIPRA), Zimbabwe African National Liberation Army (ZANLA), and the Rhodesian Army . While Western media outlets praised Mugabe's efforts at reconciliation with the white minority, tension soon developed . On 17 March 1980, after several unsuccessful assassination attempts Mugabe asked Walls, "Why are your men trying to kill me?" Walls replied, "If they were my men you would be dead ." BBC news interviewed Walls on 11 August 1980 . He told the BBC that he had asked British Prime Minister Margaret Thatcher to annul the 1980 election prior to the official announcement of the result on the grounds that Mugabe used intimidation to win the election . Walls said Thatcher had not replied to his request . On 12 August British government officials denied that they had not responded, saying Antony Duff, Deputy Governor of Salisbury, told Walls on 3 March that Thatcher would not annul the election . </P> <P> Minister of Information Nathan Shamuyarira said the government would not be "held ransom by racial misfits" and told "all those Europeans who do not accept the new order to pack their bags ." He also said the government continued to consider taking "legal or administrative action" against Walls . Mugabe, returning from a visit with United States President Jimmy Carter in New York City, said, "One thing is quite clear--we are not going to have disloyal characters in our society ." Walls returned to Zimbabwe after the interview, telling Peter Hawthorne of Time magazine, "To stay away at this time would have appeared like an admission of guilt ." Mugabe drafted legislation that would exile Walls from Zimbabwe for life and Walls moved to South Africa . </P>
