Fourth day in hospital for Mandela

Former South African president Nelson Mandela is spending a fourth day in hospital, where he is being treated for a recurring lung infection.

There was no official update on the 94-year-old this morning. The government has previously said he is in a serious but stable condition.

A foundation led by retired archbishop Desmond Tutu has described Mr Mandela as an "extraordinary gift" and offered prayers for his comfort and dignity.

Mr Mandela, leader of the anti-apartheid movement, spent 27 years in prison during white racist rule. He was freed in 1990, and and then embarked on peacemaking efforts during the tense transition which saw the demise of the apartheid system and his own election as South Africa's first black president in 1994.

He is being treated in a hospital in the capital, Pretoria.
