Russia’s embassy in London States it wants a meeting with Foreign Secretary Boris Johnson over the poisoning of ex-spy Sergei Skripal.

In a statement on Saturday, the embassy stated its negotiations with the UK’s Foreign Office had actually been “absolutely unacceptable.” It stated it was “due time” for a meeting between Johnson and Ambassador Alexander Yakovenko to go over the examination and other concerns.

The Foreign Office states it will react “in due course.”

Sergei Skripal and his child Yulia were discovered unconscious on March 4 in the English city of Salisbury after being poisoned with a nerve representative. Medical professionals say they are now in stable condition.

British authorities say Russia lagged the military-grade nerve representative. Russia denies the allegation.

The case has actually triggered a diplomatic crisis in between Moscow and the West.
