In the context of the Russo-Ukrainian War, many Russian diplomats and embassy officials were declared personae non gratae by countries around the world in 2022, and many foreign diplomats were also formally asked to leave Russia after their accreditation was cancelled.

Persona non grata means "an unwelcome person" in Latin. In the context of diplomacy or international relations, a persona non grata declaration on a foreign citizen, usually a diplomat who otherwise has a privilege of immunity, is barred from entering the country which issued the declaration.^[1]

Russian diplomatic posts

In 2018 Russia provided diplomatic cover in 145 countries with 242 diplomatic posts (embassies, consulates and trade missions).^[2]

2022 invasion of Ukraine

The Russian invasion of Ukraine in 2022 resulted in an unprecedented reaction in diplomatic circles against Russian diplomats; over 200 were expelled by 5 April 2022, just days after the disclosure of the killing of civilians in the Bucha massacre.^[3] The declared intention was to limit Russia's ability to destabilize the EU and NATO countries.^[4]

The decisions came after a dramatic increase in Russian malign activities, including the 2018 Novichok poisoning of Sergei and Yulia Skripal, and a number of countries, were led by the United Kingdom, which expelled 16 diplomats, and the United States, which expelled 60 diplomats it claimed were intelligence officers.^[5] Sixteen EU countries expelled 33 Russian diplomats on 26 March 2018.^[6] Over 150 Russian diplomats were expelled in 2018.

The UK did not participate in the 2022 expulsions as it had already reduced the Russian embassy size in 2018 and reduced staffing at its embassy in Moscow. Canada and Australia gave similar reasons.^[7]

Russia initially responded that these actions were short-sighted and would further complicate communications and inevitably lead to retaliation.^[8] Sergey Lavrov, Russia's Minister of Foreign Affairs, lamented in October 2022 that "There is neither point nor desire to maintain the previous presence in Western states. Our people work there in conditions that can hardly be called human," “Most importantly, there’s no work to do since Europe decided to shut off from us and sever any economic cooperation. You can’t force love."^[9]

Within a year, around 600 diplomats from Russia would be expelled.

Post June 2022

Additional Russian diplomats were declared personae non gratae later in 2022, including 70 by Bulgaria, for espionage, and by Australia,^[51] where a spy ring was uncovered, taking the total to nearly 600 by January 2023,^[52] with additional tit-for tat removals of diplomats by Russia.

The operation of Russian embassy's has become more difficult. Problems experienced, include bank account access in the USA,^[53] flights,^[54] visas^[55] and the downsizing of previously agreed staffing levels.

In September 2022 Montenegro expelled six Russian diplomats uncovered in an investigation into spying, Russia responded by closing their consulate in Podgorica, Montenegro, leaving just an honorary consul in Budva.^[56]

In December 2022 diplomatic relations between Lithuania and Russia were downgraded to the level of acting Chargé d'affaires after the Russian ambassador was expelled and the Lithuanian ambassador recalled.^[57]

In January 2023 Russia expelled the Estonian ambassador, resulting in Estonia expelling the Russian ambassador in their country and Latvia, in a show of solidarity, doing likewise to the Russian ambassador in Latvia, which provoked a similar response from Moscow regarding the Latvian ambassador.^[58]

The Netherlands closed its consulate in St Petersburg in February 2023 and along with a number of countries limited the number of Russian Embassy staff to the same as their country's embassy in Moscow.^[59]

By March 2023 8 Russian diplomats had been added to Serbia's total of accredited diplomats, a number of these had been expelled from other EU countries.^[60]

Switzerland considers 1 in 3 of the 221 Russian diplomats are spies but did not expel any Russian diplomats in 2022 although one resigned because of his disagreement with Moscow.^[61][62][63]

In April 2023 Norway reduced the number of Russian diplomats by expelling 15,^[64] followed by Germany with mass expulsions, reputed to be 30, and reducing the number of authorised diplomats in the country ^[65] and closing four of the five Russian Consulates in Germany.

In June 2023 Iceland suspended its embassy in Moscow and asked Russia to reduce their embassy in Reykjavik until relations are normalised.^[66] Finland expels 9 believed to be intelligence gathering.^[67] Romania also told Russia to reduce its embassy staff by 51, because of vacancies, 40 diplomats and technical staff departed in early July.^[68] Moldova then evicted 45 Russian diplomats, reducing the embassy to 25, the same as the Moldovan embassy in Moscow.^[69]

Australia passed laws to cancel a lease in June 2023 to block Russia building a new Embassy within 400m of the Australian parliament building, citing concerns of spying.^[70]

Effect of expulsions

Kremlin intelligence agencies have suffered a major blow as a result of the expulsion of intelligence agents who had been working in embassies.^[71] The head of Britain’s MI6 foreign intelligence service believed that roughly half of Russia’s spies in Europe, working under diplomatic cover, were expelled by July 2022.^[72] Ken McCallum, the director general of Britain's MI5, said in November 2022 in an annual speech outlining threats to the United Kingdom that this year 400 of the 600 Russians officials that had been expelled from Europe, were judged by his agency to be spies.^[73]

Finland believes, after a year, that it has its espionage issues under control after the expulsion of Russian diplomats and the refusal to issue visas.^[74] On the other hand those countries who have not expelled many Russian's including Austria, with 180 Russian diplomats and Switzerland with 220, are very active spy centres.^[75][76]
