Ex-spy's condition deteriorates Ex-spy's condition deteriorates
(20 minutes later)
There has been a "major deterioration" in the condition of former Russian spy Alexander Litvinenko, doctors said. There has been a "dramatic deterioration" in the condition of former Russian spy Alexander Litvinenko, doctors have said.
Mr Litvinenko, 43, is now in a "very serious" condition in intensive care at University College Hospital in London. Mr Litvinenko, 43, is now critically ill in intensive care at University College Hospital in London, after suffering a heart attack overnight.
Earlier, it emerged that X-rays had revealed three "objects" apparently in his system, but a friend said these were shadows of no medical concern. Critical care head Geoff Bellingham said it was unlikely the ex-KGB agent was poisoned by thallium.
Police, who have said they suspected "deliberate poisoning", said there had been no significant developments. The Kremlin and Russian security services have denied any involvement.
Unusual objects Friends of Mr Litvinenko have claimed he was poisoned in London earlier this month because of his criticism of Russian President Vladimir Putin.
Dr Bellingham said he was "concerned by speculation in the media by people who are not directly involved" in the care of Mr Litvinenko.
Reports of three objects found on x-rays of the patient were "misleading" and were almost certainly shadows caused by Prussian Blue, used to treat thallium or caesium poisoning, he said.

Police, who have said they suspected "deliberate poisoning", said there had been no significant developments in the case.
Mr Litvinenko's friend Alex Goldfarb said: "I have seen Alexander through the window, he is heavily sedated, and he is on a ventilator because overnight he went into a heart failure, although the doctor said that his heart is not damaged.Mr Litvinenko's friend Alex Goldfarb said: "I have seen Alexander through the window, he is heavily sedated, and he is on a ventilator because overnight he went into a heart failure, although the doctor said that his heart is not damaged.
"The situation could get better but his chances are obviously decreased now because while he is on this ventilator machine it would be much more difficult to speak about his bone marrow transplant which until today was a major problem for the doctors.""The situation could get better but his chances are obviously decreased now because while he is on this ventilator machine it would be much more difficult to speak about his bone marrow transplant which until today was a major problem for the doctors."

Earlier a hospital source told the BBC that X-rays had shown up three unusual objects of dense matter in his intestines that he apparently swallowed.
But Mr Goldfarb said: "The reporting that it was objects and foreign bodies that he had swallowed are totally baseless at this point."
The hospital said Mr Litvinenko was in intensive care in order to receive cardiac monitoring and nutrition and pain relief support.
"He can also be more effectively isolated to protect him against infection following the damage to his immune system," a statement said.
"Our investigations into the cause of his condition continue and we are not willing to make any further statement on this until we have more concrete information."

Initial reports said Mr Litvinenko was poisoned with the heavy metal thallium, although medical opinion has not been conclusive and the theory that some form of radioactive material was used has also been suggested.
