Positive signs: Nelson Mandela is 'showing great improvement', according to his ex-wife . Nelson Mandela is responding to touch and trying to open his eyes, his daughter said today, adding: 'He's still there.' The former South African president is said to be on life support after his condition deteriorated over the past few days, but a government spokesman said that he 'improved' overnight and is now 'stable'. His eldest daughter Makaziwe said that when she went to see him in hospital this morning he was still responsive and conscious. 'I won't lie, it doesn't look good,' she told SABC. 'But if we speak to him, he responds and tries to open his eyes. He's still there. He might be waning off, but he's still there.' Mr Mandela's granddaughter Ndileka said he was 'stable', and thanked the well-wishers from around the world who have sent their support.

In the Eastern Cape . province, where Mr Mandela grew up, a traditional leader said that the time was . near for the former leader, who is also known by his clan name, Madiba. 'I am of the view that if Madiba is . no longer enjoying life, and is on life support systems, and is not . appreciating what is happening around him, I think the good Lord should . take the decision to put him out of his suffering,' said the tribal . chief, Phathekile Holomisa. 'I did speak to two of his family . members, and of course, they are in a lot of pain, and wish that a . miracle might happen, that he recovers again, and he becomes his old . self again,' he said. 'But at the same time they are aware there is a limit to what miracles you can have.' Scroll down for video .
