This is the amazing moment when the two Russian novichok killers made show windows in Salisbury minutes after they tried to assassinate former double agent Sergei Skripal and his daughter.
The first footage seen of the murderers, obtained exclusively by MailOnline, shows the two men who seem relaxed and in good spirits as they strolled down the street towards the Salisbury station to make their escape.
Wearing clothes for the winter, we see Alexander Petrov and Ruslan Boshirov passing by the collectibles of the Dauwalders and the rare stamp store before getting distracted by the showcase.
Petrov is carrying a backpack, a black woolen hat and a blue coat, while Boshirov is wearing a dark jacket and a baseball cap.
Seeming to forget their mission, they examine the showcase in detail, talking enthusiastically about collectors' items.
Then they approach the entrance of the store as if to make a purchase, before realizing that the store is closed and continuing to the Salisbury train station and escape.
This is the amazing moment when the two Novichok assassins made their purchases in the windows of Salisbury, minutes after having stained the Skripals latch.
Something in the store's exhibit caught the attention of Alexander Petrov (dressed in a woolen cap and a blue coat) and arrested fellow murderer Ruslan Boshirov (in the cap)
Petrov speaks to the ear of his fellow murderer while they look at the Dauwalders showcase and the coin collector shop
Then, the couple looks towards the shop door, since they seem to be considering going in to observe more closely the article they have been examining
Petrov seems to be heading towards the door of the store before realizing that the place is closed and the men continue walking towards the Salisbury train station to take a train back to London.
The two Russian spies who were wanted for the poisoning of Novichok in Salisbury carried passports with the names of Alexander Petrov and Ruslan Boshirov, but the police say it is unlikely to be their real names.
The killers were looking at a collection of old coins in the window, the shopkeepers confirmed.
Paul Dauwalder, owner of the well-known business, said: "To be honest, they seemed pretty clumsy. The coins are not valuable, we would not keep them in the window.
"It's a continuous viewing window that often draws attention, there are some foreign currencies, Victorian cents, that sort of thing, maybe the Russians were looking for.
"It was a Sunday and they had just tried a murder, but they still tried to get into the store, obviously they were fans of the coins.
They could be killers, but that does not mean they're intellectually dead. From the way they behaved, they looked like coin enthusiasts or collectors.
"People often spend hours checking those boxes of coins, it's not unusual, it seems we even attract Russian killers.
His son, Chris, 28, said: "There's no danger of contamination since they did not come in. We have a window cleaner once a week and it's still fine, so it's probably safe."
"They looked like ordinary men," Paul added. "If it had been midweek and we were open, they would have entered the store and we would have served them."
& # 39; The mind gets confused. I'm glad we were closed.
The exclusive filming provides an idea of the relaxed mentality of the two murderers, whom the prime minister claimed to have worked for Russia's GRU military intelligence service, minutes after they carried out an assassination attempt.
While the couple bought in the windows, the former spy Skripal and his daughter Yulia were a few hours away from being hospitalized, in a chain of events that would lead to the death of the drug addict Dawn Sturgess, 44, and a new loss in the Relations between Russia and Great Britain.
By the next day, the assassins would return to Russia, while the police frantically sealed the contaminated parts of Salisbury and began the persecution.
It would be another six months before their identities were finally made public by the British authorities.
The exclusive footage provides an idea of the relaxed mentality of the two murderers, which the prime minister said worked for the military intelligence service GRU of Russia, minutes after they carried out the assassination attempt.
Just a few minutes before this recording was recorded at 1.49pm on Sunday, March 4, the two men allegedly sprayed Russian nerve agent Novichok on the door handle at the home of double agent Sergei Skripal and his daughter Yulia in Salisbury.
The men arrived in the United Kingdom on Friday, March 2 and stayed at the City Stay Hotel in Bow, east of London. They visited Salisbury on Saturday, March 3 for a few hours before going to the city of Wiltshire for the second time on March 4 when these images were taken.
It occurs when the British security minister said today that the Russian president, Vladimir Putin, is the maximum responsible for the attack of the nerve agent Novichok carried out in England.
Britain has vowed to take revenge on the Russian president by ordering a covert war as the prime minister accused two of his agents of carrying out the mission in March.
Security Minister Ben Wallace said today that he is "100 percent sure" that the men named carried out the attack and claimed that Vladimir Putin is ultimately responsible for the actions of his spies, but added: "This was more Johnny English than James Bond. "
He said: "Ultimately he does, insofar as he is president of the Russian Federation and it is his government that controls, finances and directs military intelligence, that is the GRU, through his minister defense. I do not think anyone can say that Mr. Putin is not in control of his state.
He added: & # 39; They [the assassins] they are members of the GRU; This is not a dishonest or independent operation. The soldiers do what they said, they take orders. Therefore, I think it is very clear that the Russian state has a great responsibility for this, along with the people who have chosen to attack British citizens and citizens in this country. "
When asked how the United Kingdom would respond, he declined to say and added: "We retaliate on our way, we are not Russians, we do not adopt the kind of aggressive, destructive and aggressive behavior we have seen, we chose to challenge the Russians in both the open space as in the undercover, within the rule of law and in a sophisticated way ".
The Security Minister also revealed how the security services know that the Russian state must have helped arrive in Britain while carrying the deadly nerve agent.
The assassins traveled with genuine Russian passports, using credible aliases and transporting novichok, which was designed and produced by the state, in a perfume bottle with sophisticated technology to stop their leak and a mouthpiece to help them use the deadly weapon.
Theresa May will take revenge of Russia with the cybernetic war, the espionage, the financial sanctions and the prohibitions of traveling, that probably will be used, said the sources.
Petrov (right) was seen smiling at Salisbury the day police believed the men stained novichok at Mr. Skripal's door
The couple was captured on CCTV at the Salisbury train station on March 3, the day before Skripal was poisoned. Scotland Yard believes that they came to the city to carry out a reconnaissance mission
Interpol has been on red alert to stop the two agents, who use the aliases Alexander Petrov and Ruslan Boshirov.
Mrs. May warned that they would be taken to Britain to be tried if they ever left Russia, but experts have said that Vladimir Putin will personally ensure that assassins never leave the country and reward them with lucrative promotions despite thwarting their attempted murder against Sergei Skripal and his daughter Yulia.
However, she acknowledged that it was futile to expect Russia to hand over the two murderers, especially since Russia has a constitutional impediment on extradition.
He violently attacked Moscow's response to the novichok attacks, saying that requests for cooperation had met with "obfuscation and lies."
Parliamentarians were told that new powers were in place to stop anyone suspected of "hostile state activity" at the border.
The Russian oligarchs linked to Putin face repression, which includes searches of private flights and investigations of "unexplained wealth" by the National Crime Agency.
Ms. May said the retaliatory action would specifically target the GRU, the organization linked to the demolition of the MH17 aircraft in Ukraine, the attacks in Syria and the electoral fraud in the United States. She said it was clear that the Salisbury attack was not a dishonest operation and must have been approved at a higher level of the Russian state.
Investigators believe they know the identities of the two military intelligence agents, but chose to publish aliases used in their Russian passports.
It has been possible to reconstruct your trip from Moscow to London, to the cathedral city of Wiltshire and back on a plane to Russia.

They are asking people all over the world to get in touch with them if they can name their faces. The police obtained national and European arrest warrants, and presented red notices from Interpol, effectively confining the couple to their homeland.
But the Prosecution Service said it would not request his extradition because the Russian state refuses to deport its citizens to face a trial abroad.
It is believed that both men are agents of the GRU, for whom Mr. Skripal was a colonel before being imprisoned for selling secrets to the West. He was taken to the United Kingdom in an exchange of spies.
In an attempt to silence the chorus of skepticism online about the case driven by the Russian trolls, the police gave a step-by-step account of the movements of the two-man assault squad.
The CCTV stills showed that Petrov and Boshirov arrived in Gatwick on Friday, March 2 and traveled through London before visiting Salisbury twice by train.
Dressed in quilted jackets, hats and carrying a backpack, the men reviewed the scene of their mission for recognition before returning the second day.
A camera caught the couple smiling and laughing a few minutes after carrying out their attack. At 10.30pm that night they were boarding an Aeroflot flight to Moscow from Heathrow, just over 50 hours after playing for the first time.
It is understood that the team of 250 detectives identified the two men as suspects in May while examining more than 11,000 hours of footage.
They were able to follow their steps carefully, driving to the City Stay Hotel, in Bow, east of London, where they spent the two nights. Forensic experts discovered a tiny trail of novichok in his room, a sample so small that it was carried away by the test swab.
