Frederick Chiluba pictured above, Zambia's first democratically elected president, has died at home at the age of 68.
Mr Chiluba was hailed as Zambia's "liberator" by his supporters when he came to office in 1991 after 27 years of single party Socialist rule.
He won praise for his economic and political reforms but was later accused of embezzlement and turning a blind eye to corruption.
The cause of his death is not known but he was known to have heart problems.
Under Mr Chiluba, Zambia was considered to be a model of African democracy and his presidency was welcomed in the West.
The former trade union leader and son of a copper miner introduced many reforms which dismantled the restrictive policies of former President Kenneth Kaunda.
But he was dogged by corruption allegations and was accused of taking an authoritarian approach to his political opponents, firing critical colleagues and jailing outspoken journalists.
He attempted to alter the constitution to allow him to run for a third term in office in 2001, but stood down after huge public protests.
Mr Chiluba was prosecuted for alleged embezzlement in 2002 but acquitted after a six-year trial.
In 2007, he was convicted of fraud by a London court and ordered to repay $58m in embezzled funds, but the ruling was never carried out by Zambia.
He spent his final years at his residence in Lusaka, confined by ill health and the confiscation of his passport by the authorities.

Frederick
Chiluba, Zambia's first elected President
Frederick Chiluba came to power as Zambia's second
president by defeating the once-revered Kenneth Kaunda in the first contested
elections in the country for more than 20 years.
Democracy flourished during his 10-year rule, but the dapper and diminutive
politician ended his career under a shadow of corruption. He was the son of a copper miner, and was born in Kitwe, in what was then the British Protectorate of Northern Rhodesia.
Working as a clerk as a young man, he joined a building and engineering workers union, and visited East Germany and the Soviet Union, but later became disenchanted with Communist ideology. He rose through the union ranks to become chairman in 1971, and became increasingly involved in politics in Zambia.
He had been a supporter of Kaunda through independence in 1964, but became disillusioned with one-party rule, and in 1980 threatened to call a strike against the regime.
Widespread support
After months of turmoil, Kaunda ordered the arrest of Chiluba and three
other union leaders, and they were held for three months, until a court ruled
that their imprisonment was unlawful.On his release Chiluba began to attract increasing support, and, in 1990, formed the Movement for Multi-Party Democracy, MMD, to oppose Kaunda's authoritarian rule.
With a bankrupt economy - foreign debt stood at more than $6.4bn (£4bn) - high unemployment and 100% inflation, he attracted widespread backing for his demands for economic reform and improved human rights.
Kenneth
Kaunda relinquished power in 1991
Only five feet tall, he was nevertheless an impressive figure who, as a
born-again Christian, brought the passion of the pulpit to his oratory.President Kaunda finally bowed to demands for free elections which were held in November 1991 and closely assessed by 2,000 local and foreign monitors, including a Commonwealth team and one led by US ex-President Jimmy Carter.
The poll was declared free and fair, and Chiluba and his party were swept to power with more than 80% of the vote.
Kaunda stepped down in what was regarded as the most democratic change of government ever seen in Africa.
Chiluba inherited enormous economic problems, aggravated by the worst drought in the country for 50 years. He set about trying to persuade the West to come to his aid in setting up a free-market economy, and promised a big sell-off of state-run enterprises.
But Zambian hopes for a bright future gradually turned to disillusionment as Chiluba began to abandon egalitarian principles and processes.
Tarnished image
Corruption became widespread at all levels and crime increased. The sell-off
of the state copper mines was botched and many of the mines company's assets
vanished into thin air.In the meantime, the free-market economy failed to deliver and three quarters of Zambia's population continued to live in poverty.
What's more, Frederick Chiluba's personal image suffered badly when he appeared to be more interested in himself than his country.
Mwanawasa:
Chiluba's successor brought charges of corruption against him
In 1996, he prevented former President Kaunda from standing against him in
the presidential elections by changing the constitution to preclude candidates
with parents born outside Zambia. Kaunda's father was from Zaire.His hounding of Kaunda was not popular either at home or among the international community.
In 1997, he imprisoned the former leader for allegedly conspiring in a coup plot against him. Chiluba released him only after pressure from Africa's elder statesmen, Nelson Mandela and Julius Nyerere.
He also tried to strip Kaunda of his citizenship.
Then Chiluba tried to amend the constitution again to enable him to run for a third term and allegedly spent a lot of money bribing people to support his cause. Nevertheless, he failed and was forced to step down in 2002.
Corruption Charges
The following year, his hand-picked successor, Levy Mwanawasa, brought more
than 100 charges of corruption against Frederick Chiluba including the theft of
$35m of public funds allegedly funnelled into private bank accounts in London.His wife Regina also faced charges of theft. Chiluba denied all charges, saying they were politically motivated. And he was acquitted after a six-year trial.
Corruption
became widespread under Chiluba
However in 2007 he was found guilty of stealing $46m (£23m) of public money
by a UK court. To his credit, under Frederick Chiluba, freedom of speech in Zambia flourished and its media became as lively as anywhere in Africa.
Though he tried to extend his tenure in power, he did not resort to state-controlled oppression to get his way.
Internationally, he helped broker a peace agreement in neighbouring civil war-torn Democratic Republic of Congo.
Perhaps Frederick Chiluba's greatest legacy is that he established a lasting principle of democracy in Zambian politics.
Frederick Chiluba afariki dunia
Rais wa zamani wa Zambia, Frederick
Chiluba, amefariki dunia, akiwa na umri wa miaka 68.
Bwana Chiluba amekuwa na ugonjwa
moyo kwa miaka kadhaa.
Rais Chiluba aliiongoza Zambia kwa
mwongo mzima katika miaka ya '90, na baada ya kustaafu alishtakiwa kwa sababu
ya rushwa.
Frederick Chiluba alipata urais wa
Zambia mwaka wa 1991, wakati Afrika inaanza kuingiia katika demokrasi ya vyama
vingi.
Kabla ya hapo alikuwa kiongozi wa
wafanyakazi.
Aliahidi kuleta mabadiliko lakini
alipochukua uongozi Zambia ilikuwa imeshafilisika, naye aliacha rushwa kustawi.
Alipojaribu kujiongezea muhula wa
tatu wa madaraka, alipingwa.
Pia alilaumiwa kuwa akipenda maisha
ya anasa.
Baada ya kuondoka madarakani mwaka
wa 2001, mrithi wake, Levy Mwanawasa, alimshtaki kwa shutuma za rushwa.
Baada ya kesi ya miaka 6 kuhusu
ubadhirifu wa mali ya taifa, Frederick Chiluba aliambiwa hakuwa na makosa. .
Lakini katika kesi nyengine
iliyofanywa katika mahakama makuu ya London, Chiluba alikutikana na hatia ya
kuiba mamilioni ya dola ya fedha za serikali ya Zambia, kwa kutumia akaunti
kwenye mabenki ya London.
