As tensions between Russia and the rest of Europe continue to boil over, Russia is expelling another 50 British diplomats.
Russian Foreign Ministry spokeswoman Maria Zakharova told Reuters that Britain would have to recall "a little over 50" of its diplomats in the country.
British Ambassador Laurie Bristow was summoned to the Foreign Ministry in Moscow on Friday.
Zakharova told Reuters: "We asked for parity.
The Brits have 50 diplomats more than the Russians."
UK Prime Minister Theresa May expelled 23 Russian diplomats from Britain earlier this month.
She did so after her government concluded that Russia was behind the poisoning of ex-spy Sergei Skripal and his daughter in Salisbury at the start of the month.
