MOSCOW (Reuters) - The decision to scale back British-Russian dialogue was a groundless and untimely decision by London, Russian Foreign Ministry spokeswoman Maria Zakharova said on Thursday, on the eve of British foreign minister Boris Johnson s visit to Moscow. Johnson s visit on Dec. 22 for talks with his Russian counterpart Sergei Lavrov to discuss international security issues will be the first visit to Russia by a British foreign minister in five years.
