Smith Hempstone later wrote that the former Prime Minister had resolved to "go down ... with all rhetorical guns blazing". This was in spite of increasingly unstable health; in June 1982 he collapsed in the House of Assembly, clutching at his side and shaking. Half a year later he had to arrange treatment in South Africa for a condition stemming from hardening of the arteries. The government's confiscation of his passport and two refusals of its return prevented him from going, so in April 1983 Smith successfully applied for a British passport. "I'll still try to get my Zimbabwean passport back," he said. "I was born here and that is the passport I should travel on." Smith regained his Zimbabwean papers after about a year. In 1984 he declared his intention to renounce his British nationality to abide by a new Zimbabwean law outlawing multiple citizenship. Britain did not recognise this legislation; according to Smith, British officials refused to take his UK passport when he tried to return it.
