Nelson Mandela 'Day Of Reflection' In South Africa, As UK MPs To Pay Tribute (VIDEO, PICTURES)

Nelson Mandela's memorial service is set to be one of the largest gatherings of international heads-of-state in many decades, with politicians, celebrities and hundreds of thousands of ordinary South Africans heading for the Soweto stadium.

Prime Minister David Cameron, as well as US President Barack Obama, French President Francois Hollande, and leaders from Brazil, Germany, India, Spain, and Australia, amongst others will attend, as well as UN Secretary General Ban Ki-moon.

Former British PMs Gordon Brown, Tony Blair and Sir John Major will also join the service.

The South African government has already said it will provide for 200,000 people to attend. Thousands have already left floral tributes, icons, and photographs across the front of the Union Buildings in Pretoria.

Others have left many thousands bunches of flowers, balloons, candles and messages for the former South African president outside Mandela's home in Houghton, Johannesburg.

The FNB Stadium was the scene of the anti-Apartheid leader's last public appearance - the closing ceremony of the 2010 Football World Cup.

Dozens of world leaders and heads of state have already confirmed their place at what is set to be one of the best-attended such events in history.

Sir Richard Branson and singer Peter Gabriel - who devised "The Elders" forum of statesmen and activists set up by Mandela - are also due.

It is part of a week of commemorative events leading up to the state funeral and interment in the ex-president's childhood village of Qunu.

Prince Charles will be among a smaller number of dignitaries travelling to the remote rural location for that service.

Political hostilities will be temporarily halted in the Commons on Monday as politicians gather to pay tribute to Mandela.

Question Time has been suspended to allow MPs to honour the memory of the former South African president who died last week.

Speaker John Bercow will make the opening address, followed by words from David Cameron and other party leaders.

The Prime Minister will later fly to Johannesburg where he is among tens of thousands due at a stadium memorial service tomorrow.

With many MPs expected to want to commemorate South Africa's first black president, the rest of the day's House business may also be scrapped.
