England’s health service said on Friday that Sergei Skripal, has been discharged from the hospital.
The 66-year-old former Russian spy, who was a former colonel in Russia’s military intelligence was poisoned by a nerve agent in Britain more than two months ago.
Skripal daughter Yulia were found unconscious on a public bench in the southern English city of Salisbury on March 4.
Britain has accused Russia of being behind the nerve agent attack and Western governments including the U.S. have expelled over 100 Russian diplomats.
Russia has denied any involvement in the poisoning and has retaliated in kind.
The Skripals were in a critical condition for weeks and doctors at one point feared that, even if they survived, they might have suffered brain damage.
But their health began to improve rapidly, and Yulia was discharged in April.
“It is fantastic news that Sergei Skripal is well enough to leave Salisbury District Hospital,” the hospital’s Chief Executive, Cara Charles-Barks, said in a statement.
Britain and international chemicals weapons inspectors have said the Skripals were poisoned with Novichok, a deadly group of nerve agents developed by the Soviet military in the 1970s and 1980s.
Russia has denied Britain’s charges of involvement in the first known offensive use of such a nerve agent on European soil since World War Two.
It has suggested Britain carried out the attack itself to stoke anti-Russian hysteria.
