"The Prime Minister thanked President Poroshenko for the Ukraine’s support and expulsion of 13 Russian diplomats. She noted that this was not just a strong signal of solidarity with the UK, but also of commitment to our collective security. The Prime Minister highlighted that the breadth and extent of the international response to Salisbury sent a clear message that Russia’s malign actions will not be tolerated," the spokesperson said.
The two leaders discussed by phone the Salisbury incident, with the Ukrainian president condemning the "appalling act" and vowing to stand in solidarity with London "in the face of Russian aggression."
Russia's relations with the United Kingdom, as well as with a number of Western states, deteriorated in early March as London accused Moscow of poisoning former spy Sergei Skripal and his daughter in Salisbury. Soon after the incident, London announced the expulsion of 23 Russian diplomatic workers. Over two dozen countries have since expelled Russian diplomats "in solidarity" with London.
Moscow has denied having any role in the case, pointing to the lack of evidence provided by London to substantiate its accusations.
