"After many reminders, the embassy received on September 25 a response from the British Home Office, which refuses to satisfy the requests by the Russian Prosecutor General's Office of March 29 and April 17 to provide legal assistance in the investigation of the criminal case opened in Russia over the murder attempt on Sergei and Yulia Skripal in Salisbury," the embassy said in a statement obtained by Sputnik.
In practice, this means that London is refusing to share any information or evidence gathered by UK Police when working on the Salisbury incident with the Russian investigators, the embassy said.
"This position has now been officially approved at the highest level and acquired a legal form," it added.
The embassy recalled that UK authorities had announced earlier that they did not intend to pursue extradition of the "suspects" and showed no interest in submitting their requests for legal assistance, which could include questioning of certain persons or provision of access to documents, so London did not aim to bring the investigation to its logical end in either Russian or UK legal framework.
"Thus, the British side has confirmed that from the very beginning the aims of its campaign around the poisoning of Sergei and Yulia Skripal lay exclusively in the field of politics and propaganda. It has nothing to do with aspiration to establish the truth and bring those responsible to justice," the embassy added.
Moscow has denied any involvement in the incident, saying London had not provided sufficient evidence to substantiate its claims.
The situation has led to an international row, with scores of Russian diplomats being expelled from the United Kingdom and other EU countries. Moscow has expelled UK diplomats from Russia in response to the country's actions.
