British Prime Minister Theresa May has launched a blistering attack on what she called Russia's efforts to "sow discord in the West," putting Moscow on notice: "We know what you are doing and you will not succeed."

In what is being described as a major foreign policy address delivered at the Lord Mayor's Banquet at Mansion House in London on Monday, May said Russia was waging "a sustained campaign of cyber-espionage and disruption."
