Days before Russian President Vladimir Putin sailed to a landslide reelection victory, British Prime Minister Theresa May accused his government of poisoning a former double agent for the United Kingdom on her soil.

Sergei Skripal and his daughter were poisoned with a chemical nerve agent. Both are listed in critical condition. 

In response, May expelled 23 Russian diplomats from the U.K. Putin denies the accusations. 

U.K. opposition Labour Party leader, Jeremy Corbyn, expressed skepticism of May’s decision, according to a report in The Guardian. Corbyn said the diplomatic row would lead to bad business with Russia, and could compromise the U.K.’s other foreign interests. Others accuse Ms. May of not doing enough to counter a growing Russian threat.
