Former Russian spy Sergei Skripal, poisoned in the United Kingdom, was discharged from a hospital in Salisbury, the National Health Service England said Friday.
The former Russian double agent and his daughter were attacked in the southern English city of Salisbury on March 4 and found slumped over on a park bench.
"Sergei Skripal was discharged from the hospital... we are happy that he is alright and so that is another great opportunity to see him", Alexander Yakovenko told reporters.
Salisbury District Hospital said that all three people hospitalised in the attack - Sergei and Yulia Skripal as well as a police officer who came to their assistance - had now been released.
"That he, Yulia and DS Bailey have been able to leave us so soon after coming into contact with this nerve agent is thanks to the hard work, skill and professionalism of our clinicians, who provide outstanding care to all our patients, day in and day out".
They have been taken to an undisclosed location for their safety.
The Skripals were poisoned with a dose of liquid nerve agent as high as 100 grams, the head of the Organisation for the Prohibition of Chemical Weapons said earlier this month.
"I want to thank the public for their support, and I want to pay a special tribute to both the clinical staff here at the trust and those who work so hard behind the scenes".
Worldwide chemicals weapons inspectors had also confirmed that the Skripals were poisoned with Novichok, a deadly group of nerve agents developed by the Soviet military in the 1970s and 1980s.
The British government blamed Russian Federation for the attack but the Kremlin denies any involvement.
Scotland Yard said that detectives from the UK's Counter Terrorism Policing network are making "good progress" in their investigation and welcomed the news that Skripal had been released from hospital.
"This is a complex investigation and detectives continue to gather and piece together all the evidence to establish the full facts and circumstances behind this terrible attack", it said in a statement. They later claimed that London was violating the rights of Russian citizens Sergei and Yulia Skripal.
Skripal is a retired military officer formerly of the Russian GRU, or military intelligence.
He moved to Britain as part of a spy swap in 2010 and has lived there ever since.
