The Kremlin said on Tuesday that former British foreign minister Boris Johnson’s contribution to UK-Russia relations was very modest.

The poisoning of a former Russian spy and his daughter in the English city of Salisbury in March has caused a crisis in relations between Moscow and London, and Britain’s top counter-terrorism officer has said a British woman, Dawn Sturgess, died on Sunday after being poisoned by the same nerve agent.

Russia denies British accusations of involvement and Kremlin spokesman Dmitry Peskov said on Tuesday that Moscow hoped reason would now prevail.

“Sooner or later we expect some reasonable explanations or arguments about the recent situation in Salisbury and the situation that followed it.”
