Zimbabwean President Robert Mugabe told Christopher Dell, the US ambassador to Zimbabwe, to "go to hell" this week after the envoy blamed the country’s economic and political crisis on mismanagement and corrupt rule. State media said Dell risked expulsion from Zimbabwe for his "undiplomatic" criticism of the government in a public lecture. The Zimbabwe Broadcasting Corporation said it had asked Mugabe for his reaction to the comments. "The president said the ambassador must go to hell. The president said: ‘I cannot even spell the word Dell with a "D" but an "H" and that is where Dell should go’," a ZBC correspondent said during a news bulletin. Dell said last week that Mugabe’s government was responsible for plunging Zimbabwe into a crisis which had left it with poverty and chronic food shortages.
