Singer George Michael has admitted that his recent bout of pneumonia was "touch and go for a while" and that he has been through the worst month of his life.

The 48-year-old star, who has returned to London following a month-long stay in a Vienna hospital, said he was "very weak" but added he feels "amazing".

In a press conference outside his home, an emotional Michael said he still has "plenty to live for".
