British Prime Minister Theresa May told Russian President Vladimir Putin on Friday that Russia must end its "irresponsible and destabilizing activity" for normal relations between the two countries to be restored.

May also told Putin that the two Russians responsible for the attack on Sergei Skripal in Salisbury last year must be brought to justice, her office said in a statement.

May said “the use of a deadly nerve agent on the streets of Salisbury formed part of a wider pattern of unacceptable behavior and was a truly despicable act that led to the death of a British citizen, Dawn Sturgess."

The comments came as May held talks with Putin on the sidelines of the G20 summit in Osaka, Japan.
