Well, here's everything you need to know...
Who died in the Salisbury Poisonings attack?
On March 4, 2018, former Russian spy Sergei Skripal and his daughter Yulia were poisoned.
The pair had came into contact with Novichok, one of the deadliest chemical weapons ever made.
The father and daughter were rushed to Salisbury District Hospital where medics fought to keep them both alive.
Yulia left on April 9, while her father remained in hospital until May 18.
Sadly, another victim, Dawn Sturgess, died eight days after she came into contact with the nerve agent.
The 44-year-old was found unconscious at her home in nearby Amesbury, alongside her boyfriend Charlie Rowley.
While Charlie survived, the couple had both handled a discarded container used to transport the poison.
Detective Sergeant Nick Bailey, who also fell ill after attending the incident, also survived after hospitalisation.
What is Novichok?
Novichok nerve agent is reportedly one of the most powerful chemicals ever.
It works by disrupting communication between nerves and muscles or nerves in the brain.
Eventually, it causes the muscles to paralyse.
It took hours for police to identify the agent as Novichok at the time of the Salisbury poisonings.
Where is Sergei Skripal now?
According to senior government sources, Sergei and Yulia have moved to New Zealand.
The pair have received new identities.
The father and daughter seemingly still receive protection from authorities.
The move comes two years after the father and daughter were first put under house arrest and guarded by British Intelligence.
