Zambian Vice-President Guy Scott has been named acting leader following the death of President Michael Sata.
Presidential elections to choose a permanent successor will be held within 90 days, Defence Minister Edgar Lungu said.
Mr Scott becomes Africa’s first white head of state since FW de Klerk in apartheid South Africa.
Mr Sata died in the UK aged 77 after receiving treatment for an undisclosed illness.
He was being treated at London’s King Edward VII hospital where he died on Tuesday night.
‘Beloved comrade’Mr Scott regularly stood in for the president at official events, but was never appointed acting president when Mr Sata was abroad – so this is his first time to officially lead the country.
- Often disparagingly referred to as the “ceremonial vice-president”
- He was born in 1944 in Northern Rhodesia after father emigrated from Glasgow to work as a doctor on the railways
- A Cambridge-trained economist, he entered politics in 1990 joining the MMD which won the first multiparty elections the next year
- As agricultural minister he oversaw the recovery from a devastating drought in 1992/93
- He joined Michael Sata’s Patriotic Front (PF) in 2001
- Appointed vice-president in September 2011 after the PF’s election victory
- As his parents were not born in Zambia a constitutional clause on parentage may nullify any attempt to run for president
Guy Scotts’s rise to Presidency
In a brief televised address Mr Scott confirmed his appointment.
“The period of national mourning will start today. We will miss our beloved president and comrade,” Reuters news agency quotes him as saying.
The president’s death comes just days after Zambia celebrated the 50th anniversary of independence from the UK.
Cabinet secretary Roland Msiska said on national TV that President Sata’s wife and son were at his bedside.
He is the second Zambian leader to die in office after Levy Mwanawasa in 2008.
Earlier this month reports in Zambia said that President Sata had gone abroad for a medical check-up amid persistent speculation that he was seriously ill.

A devout Catholic, Mr Sata had worked as a police officer, railway man and trade unionist during colonial rule. After independence, he also spent time in London, working as a railway porter, and, back in Zambia, with a taxidermist company.
At the fourth attempt, Mr Sata won presidential elections in 2011. At first he looked as if he would keep promises to tackle corruption and create jobs and prosperity. But his term in office was marred by a crackdown on political opposition and a decline in the economy.
He had rarely been seen in public since returning from the UN General Assembly last month, where he failed to make a scheduled speech.
After he left the country, Defence Minister Edgar Lungu was named as acting president.
Mr Scott is of Scottish descent and his parents were not born in Zambia, so he may not be able to run for president in January because a constitutional clause on parentage could nullify his candidacy.
