A Briton on hunger strike in a Greek prison is in a "very serious" condition according to a medical report, released on Friday.
Briton Simon Chapman says evidence was planted
Six of his fellow hunger strikers are in a critical condition.
Simon Chapman, 30, from Basildon, Essex, was demonstrating with anti-capitalist protesters at the European Union summit in Thessaloniki in June, when he was arrested.
He was later charged with possessing Molotov cocktails, an axe and a hammer.
But Mr Chapman says they were planted on him by the police, and says he has video evidence to prove it.
If convicted, he could face up to 25 years in prison.
He began his hunger strike on 5 October and this Sunday begins his eighth week without food.
About 10,000 protesters gathered for the summit
On Friday night, his brother Chris Chapman, told BBC News Online he was "very concerned" about his Simon's condition.
Four fellow anti-globalisation protesters on
hunger strike are said to be in a "critical" condition, according to the medical report published on Friday.
Greek Spyros Tsitsas, 23, and Spaniard Carlos Martinez, 25, are said to be the most seriously ill, according to the report drawn up by two Athens doctors appointed by lawyers.
The report says that two of their co-accused, Spaniard Fernado Perez 22, and Syrian Sueiman Daikduk, 34, are also critical.
The protesters began their hunger strike as a
protest at a decision not to allow them to be released on bail ahead of their trial, the date of which has yet to be fixed.
They have all been indicted for possession of explosives.
Doctors said in their report that they recommend all five be urgently transferred to one of the capital's hospitals.
Up to now the hunger strikers have been treated in the high-security Korydallos prison hospital, with the exception of Mr Perez, who was admitted to a public sector hospital in a suburb of Athens in mid-November.
