THREE FORMER PMs TO TRAVEL WITH HARPER

JOHANNESBURG - South Africa expects overwhelming crowds and a host of world leaders to attend services honouring late President Nelson Mandela, though with the ceremonies only days away officials acknowledged Saturday they couldn't offer any specifics.

Across the country, South Africans already have begun honouring Mandela, who died Thursday at age 95, with hundreds flocking to the street outside his home in the Johannesburg neighbourhood of Houghton.

Official services begin Tuesday with a major memorial planned at FNB Stadium on the edge of Soweto. Minister in the Presidency Collins Chabane told journalists Saturday he expects massive crowds far beyond what the stadium's 95,000-person capacity could hold. He said there would be "overflow" areas set up.

"We can't tell people not to come," he said.

He couldn't offer specifics about how crowds would arrive there with all roads to the venue closed by police or who would serve as a master of ceremonies.

At Mandela's house in Houghton, hundreds of people gathered Saturday where they sang liberation songs and homages to Mandela. They walked through the streets of Houghton, past expansive, stately homes carrying bundles of flowers and images of Mandela. One young girl, held by her father, carried flowers torn from a garden, weeds included.

Precious Ncayiyana, a pharmacist, carried a painting of Mandela made from old newspaper clippings about him. His left eye bore the number 4664, Mandela's former inmate number, while his right eye said Madiba, his clan name.

Ncayiyana said she planned to drive the painting's artist to Pretoria so he could make a painting of the leader's body lying in state.

"It's my way of contributing to Madiba's legacy. He's gone, but his spirit lives on," she said.

As the chanting and cheering behind her grew louder, she raised her voice to add: "If you see someone you can help, it doesn't cost anything. ... That's what he taught us."

Those planning Mandela's funeral include the former president's family, the federal government, the military and the African National Congress political party. Despite some prior planning by authorities as Mandela grew frail and suffered bouts of hospitalization in recent years, many of the details remain up in the air.

It's unclear which ceremony world leaders will attend, either Tuesday's stadium memorial or the planned funeral service Dec. 15 in Qunu, the Nobel Peace Prize laureate's rural hometown in Eastern Cape Province. Chabane said South African officials were briefing diplomats Saturday about the arrangements.

U.S. President Barack Obama and his two predecessors, George W. Bush and Bill Clinton, already have indicated they will attend services in South Africa honouring Mandela.

Mandela's body won't be at the stadium event Tuesday, Chabane said. His body will rest in state Wednesday, Thursday and Friday at the Union Buildings in Pretoria, South Africa's capital. Mandela's body will held overnight those days at 1 Military Hospital on Pretoria's outskirts, Chabane said. He called on residents to line the streets to serve as an honour guard as Mandela's body passes twice each day.

ANC members will hold a ceremony on Dec. 14 at Waterkloof Air Force Base near Pretoria before Mandela's body is flown to Qunu, Chabane said.

Sunday has been declared a national day of prayer and reflection over Mandela's death. The government has announced that a special sitting of the two houses of parliament will be held on Monday to pay tribute to Mandela, the country's first black and democratically-elected president.

Tributes to the former anti-apartheid activist continued to pour in from around the globe Saturday. Zimbabwean President Robert Mugabe, who has been in power since his country's independence from Britain in 1980 and supported Mandela's ANC during its struggle against the apartheid regime, paid his first public tribute to the deceased leader on Saturday.

Despite himself being accused by critics of increasingly authoritarian rule, Mugabe praised Mandela as a champion of democracy and "an unflinching fighter for justice."

"Mr. Nelson Mandela's renowned and illustrious political life will forever remain a beacon of excellence," Zimbabwe's state-run newspaper The Herald quoted Mugabe as saying.

The Prime Minister's Office says three former PMs have confirmed they will accompany Stephen Harper to South Africa to pay final respects to Nelson Mandela.

The PMO says Harper will leave for Johannesburg on Sunday with a delegation that will include Jean Chretien, Kim Campbell and Brian Mulroney.

Harper will attend a public memorial for Mandela on Tuesday in Johannesburg, as well as his lying in state in Pretoria on Wednesday.
