Kremlin spokesperson said on Thursday that allegations made by United Kingdom's intelligence about Russia seeking to create "mayhem on British and European streets" are "absolutely unsubstantiated" and "groundless."
"We are not prepared to accept unsubstantiated accusations, we do not intend to accept them, and we urge you to treat them as some kind of completely sweeping criticism that does not deserve attention," Peskov told reporters.
On Wednesday, Chief of British intelligence agency MI5 Ken McCallum claimed that the UK's support for Ukraine makes it "loom large in the fevered imagination of [Russian President Vladimir ]Putin's regime" and accused Russia's Main Directorate of the General Staff of the Armed Forces of the Russian Federation (GRU) of being on "a sustained mission to generate mayhem on British and European streets" by acts of "arson, sabotage and more."
