Russian dissident Alexei Navalny is in a stable condition and is undergoing further tests following a suspected poisoning, his spokeswoman has told Sky News.
Mr Navalny was visited by his wife, Yulia Navalnaya, and a top aide on Sunday in a Berlin hospital where he is being treated by German doctors.
His family and medics would not comment on his illness or treatment while they await the results of extensive diagnostic tests, although Sky’s defence correspondent Alistair Bunkall said he “suspects we will hear more as the days go on”.

The politician and corruption investigator, who is one of Russian President Vladimir Putin’s fiercest critics, was taken into intensive care in the Siberian city of Omsk on Thursday after falling in during a flight from Tomsk to Moscow.
He was flown to Germany on Saturday for further treatment after doctors said he was stable enough to be transferred.
Supporters believe Mr Navalny was given tea laced with poison, and that the Kremlin is to blame both for his illness and for the delay in transferring him overseas.
Mr Navalny’s own doctor, Yaroslav Ashikmin, who has treated him since 2013, said the politician did not have any underlying illnesses and had always been in good health.

Doctors in Omsk have denied any Kremlin interference and suggested Mr Navalny’s illness was the result of a metabolic disorder.
They said a drop in blood sugar may have caused him to lose consciousness.

Russian authorities said tests done so far have not shown any poisons in his system.
Critics suggest the delay to Mr Navalny’s transfer was to make sure the poison was undetectable by the time he was examined by German doctors.
The politician’s family had attempted to move him on Friday morning, flying in a team of German specialists with advanced medical equipment, but doctors in Omsk initially said he was too unstable to move.
The Kremlin has denied the delay was political and said it was purely a medical decision.
Mr Navalny has frequently been detained by law enforcement and was attacked by several men who threw antiseptic in his face in 2017.
Last year, his supporters suspected he had been poisoned in prison while serving a sentence on charges of violating protest regulations.
Doctors at the time said he had suffered a severe allergic reaction and sent him back to detention the following day.
Outspoken critics of the Russian state have previously been targeted in similar ways, with the Kremlin accused of being behind the attacks.
Previous high-profile cases include the 2006 assassination of Alexander Litvinenko and the March 2018 novichok poisoning attack on Sergei and Yulia Skripal in Salisbury.
