PARIS (AFP) - Two people found in a critical condition in south-western Britain were exposed to the same nerve agent that poisoned an ex-Russian spy and his daughter earlier this year, police have said, although they have not established a link between the two incidents.

The poisoning in March of Sergei and Yulia Skripal caused a major diplomatic fallout with Russia.

Here is a summary of the main developments:

Slumped on a bench

On March 4, 66-year-old former spy Sergei Skripal and his daughter Yulia, 33, are found unconscious, slumped on a bench in the city of Salisbury.

Three days later, with the Skripals in hospital in critical condition, police say the pair were poisoned with a highly-toxic nerve agent.

London accuses Moscow

On March 12, British Prime Minister Theresa May says it is "highly likely Russia was responsible".

She says the military-grade nerve agent was identified as belonging to a group known as Novichok ("Newcomer"), developed by the Soviet government towards the end of the Cold War.

Moscow rejects the claim.

Diplomatic backlash

On March 14, London says Moscow is "culpable" and pledges to expel 23 Russian diplomats.

It suspends high-level diplomatic contact with Moscow and says it will keep royals at home during the 2018 football World Cup in Russia.

The following day Britain, France, Germany and the United States blame Russia in a rare joint declaration.

Yulia Skripal has spoken to Reuters for the first time on camera since recovering from a poisoning on UK soil that Britain has blamed on Russia. Yulia was hospitalised along with her father Sergei Skripal in a nerve agent attack in March.

Russian riposte

On March 17, Moscow says it will expel 23 British diplomats and halt the activities of the British Council, with Russian President Vladimir Putin denouncing the British accusations as "rubbish".

On March 20, experts from the Organisation for the Prohibition of Chemical Weapons (OPCW) take samples of the toxic substance.

Two days later, a police officer exposed at the same time as the Skripals is discharged from hospital.

European Union leaders also blame Moscow for the attack.

Mass expulsions

On March 26, a raft of Britain's allies announce they are expelling Russian diplomats in a coordinated action.

Washington says it is throwing out 60 Russian "spies" and closing the Russian consulate in Seattle.

By March 27, the number of Russian diplomats expelled from various countries and posts reaches 150.

Two days later, Russia announces the expulsion of 60 US diplomats and the closure of the US consulate in Saint Petersburg.

On March 30 it says diplomats from another 23 countries, almost all EU members, will have to leave. Up to 50 more British diplomatic staff will be kicked out, it indicates the following day.

Source not verified

On April 3, the British military facility analysing the nerve agent says it has "not verified the precise source".

The Kremlin demands an apology and on April 4 its foreign intelligence chief says the case is a "grotesque provocation... concocted by the British and American security services".

At an April 5 meeting of the OPCW, a Russian bid to hold a joint enquiry with Britain into the poisoning fails, with London saying it would be "perverse".

At the UN Security Council, Russia again hotly denies responsibility. "It's some sort of theatre of the absurd," says its ambassador.


On April 6, the hospital treating Sergei Skripal says he is "improving rapidly" in the first official news of his condition.

On April 10, officials say his daughter has been discharged.

Two days later, the OPCW confirms Britain's findings on the nerve agent but does not apportion blame.

In an April 13 letter, National Security Adviser Mark Sedwill says Britain has information that Russian intelligence had been spying on the Skripals for at least five years before the attack.

On April 17, an operation to clean up affected areas of Salisbury begins with 190 specialist military personnel.

New alert

On July 4, police reveal that two people are in a critical condition in hospital after being found unconscious on June 30 at a house in the village of Amesbury, around 12km, from Salisbury.

Later the same day they confirm that the man and woman have come into contact with Novichok. The situation is declared a "major incident" and counter terrorism police take the lead in the investigation Neil Basu, head of counter-terrorism police, says: "The possibility that these two investigations might be linked is clearly a line of enquiry for us."
