Who's Russian double spy Sergei Scripal?

The 66-year-old after being poisoned has been taken to the hospital, where his state of health is under very difficult conditions.

Scribal lived in Salisbury, who served in the Russian Army intelligence as a colonel until 1999.

After that, he worked as foreign minister until 2003, reports “Sky News” Transmission Periscope.

But he was arrested in Moscow a year later and admitted that he was recruited by British intelligence in 1995.

He said that information he had provided to British intelligence about Russian agents in Europe had made in exchange for $100,000.

During the trial, Russian media quoted the country's security agency as saying the damage to Scripal activities was comparable to that caused by Oleg Penkovsky, a colonel spying on the US and Britain, who was executed in 1963.

In 2006, Scripal was convicted of drilling 13 years into a maximum security prison.

But he was released in 2010 and given refuge in Great Britain as part of a spy exchange between Russia and the US.

Ten Russians were expelled from the US, and Scripal was one of four freed Russians, with whom the two groups were exchanged at Vienna Airport.

One of the Russian agents issued by the US in the deal was Anna Chapman, who had married a British man and lived in London for several years.

The three Russians released in the deal were Alexander Zaporozsky and Igor Sutyagin, both convicted of spying on the US, and Genad Vasilenki, who was imprisoned for illegal possession of arms. /Periscopi/
