The British Foreign Secretary Dominic Raab, said on Sunday that he was absolutely certain of the UK 's allegations that the Russia has been involved in targeting coronavirus research by hackers, calling the act "outrageous and reprehensible."
Moscow immediately dismissed the allegations as "baseless" and its ambassador to London said in a British television interview on Sunday that the allegations did not make sense.
However, Raab said the three countries' conclusion came from assessments by the British National Cyber Security Center (NCSC) and its counterparts in USA and Canada.
For his part, o Andrei Kelin, who was appointed Moscow's top envoy to Britain last November, mocked the allegations in an interview with the BBC.
He also denied Britain's allegations that Russian hackers had tried to interfere in the elections which took place last year in the country.
Raab said on Thursday that malicious operatives working for the Russian government had leaked trade documents between Britain and the United States in a bid to overturn the election results.
Russia and Britain have been at loggerheads since Moscow was accused of trying to kill the double agent Sergei Skripal, with the help of a powerful military agent in 2018.
The attack in Salisbury, in the south west of England, took place 12 years after the poisoning of the former spy Alexander Litvinenko in London.
Russia has once again denied any involvement, and Kelin said the country is ready to confront the controversy.
