“As far as we understand, we are talking about Rowley’s most preliminary plans. A lawsuit specifically against the Russian government is considered by his lawyer only as “one of the options,” the diplomatic department said.

Diplomats noted that they share the man’s desire to establish the truth around the poisoning of himself and the deceased Don Sturgess.

The embassy added that the British authorities did not provide the Russian side with answers to many questions, including those concerning Rowley himself.

“It is easy to see that the answers to these questions should not be given by the British, but by the British authorities,” the diplomatic mission emphasized.

They also said that the Russian law enforcement system from the very beginning was ready to fulfill its duties "in the context of the poisoning in Salisbury of two citizens of our country."

“As for the hypothetical lawsuit against Russia, we recall that, by virtue of the principle of sovereign equality, the state of Russia is beyond the jurisdiction of the courts of the state of Great Britain, and vice versa,” the embassy concluded.

Earlier media reported that Charlie Rowley intends to file a lawsuit against Russia and demand compensation of £ 1 million.

On April 7, Russian Ambassador to Great Britain Alexander Yakovenko met with Rowley and his brother Matthew.

In a conversation with RT, the diplomat told the details of the meeting. According to Yakovenko, Rowley does not have a specific position in the case of the Amesbury incident and he does not consider Russia to be involved.

In July 2018, two people were injured in British Amesbury, presumably due to exposure to an unknown substance.
