Former President Nelson Mandela spent a second night at a Pretoria hospital last night.

ANC members in Gauteng sang for Mandela, 94, and wished him a speedy recovery just before the start of their special provincial general council in Alberton on the East Rand yesterday.

"May he recover speedily. He remains an inspiration to us and we wish him a long life," said provincial chairman Paul Mashatile, before leading members in song praising Mandela, and declaring "there is no one like him".

Family members also visited him at the hospital yesterday, including his children and grandchildren.

News of his hospitalisation this weekend has had many people worried, with some churning out some of his quotes on Twitter.

Well-wishes for the Nobel Peace Prize laureate poured in from across the world at the weekend.

Yesterday worshippers at the Regina Mundi Catholic Church in Rockville, Soweto, gathered to offer prayers for the icon.

Congress of South African Trade Unions (Cosatu) spokesman Patrick Craven sent his best wishes to Mandela and his family. He said he hoped there was really no cause for alarm.

Yesterday morning, President Jacob Zuma visited Mandela, a day after he was airlifted to an unnamed hospital in Pretoria to undergo medical tests.

"He found him comfortable and in good care," Zuma's office said.

After Mandela's admission on Saturday the Presidency issued a statement containing assurance that there was "no cause for alarm" and that he was admitted for tests "consistent with his age".

It is believed he is admitted at 1 Military Hospital in Pretoria.

Mandela's healthcare needs have been taken over by the military since his respiratory infection in 2011.

This is his second hospitalisation this year. Mandela was first hospitalised in February after complaining of abdominal pains. He is growing frail and has not made a public appearance since the 2010 Fifa Soccer World Cup. Mandela has since moved from his Houghton, Johannesburg, residence to his childhood hometown of Qunu in Eastern Cape.
