There were conflicting accounts of his condition. The Sun on Sunday said he was "close to death" after suffering what the paper described as a "catastrophic reaction to alcohol withdrawal". It quoted an unnamed source saying that "his vital organs are shutting down". The Daily Star Sunday said that while Gascoigne was still in intensive care, his life was no longer in imminent danger.
Gascoigne was seriously ill on Saturday night but is said to be out of immediate danger.
Former team-mate Gary Lineker said that his friend is 'struggling'.

The Match of the Day presenter wrote on Twitter: 'Gazza is struggling, Let's hope he can hang on in there.'
According to sources, his condition has stabilised, although it is not clear when he will be well enough to attend his rehab course.
A group of celebrity friends – including Chris Evans, Gary Lineker and Piers Morgan – had paid for Gascoigne to attend the clinic, which costs about £30,000 for an eight-week stay.
Since then a number of England players, among them Wayne Rooney, have stepped forward with offers of funds.
