The new measures are seen as punishment for Britain's calls on allies to expel Russian diplomats.

"We asked for parity. The British have 50 diplomats more than the Russians," foreign ministry spokeswoman Maria Zakharova told AFP. 

On Friday, Moscow summoned British ambassador Laurie Bristow, giving London a month to cut the number of diplomatic staff to the same number Russia has in Britain. 

Bristow had been handed a protest note in connection with the "provocative and unfounded actions of the British side which instigated the unwarranted expulsion of Russian diplomats from a variety of states," the foreign ministry said Friday.

In all, more than 150 Russian diplomats have been ordered out of the US, EU members, NATO countries and other nations in solidarity with Britain over the poisoning of former spy Sergei Skripal and his daughter on British soil in early 

Earlier this month Russia expelled 23 British diplomats, closed a British consulate in Saint Petersburg and halted the activities of British Council.

They came after Britain expelled 23 Russian diplomats and suspended high-level contacts, among other measures.

On Friday, Russia expelled diplomats from 23 other countries - most of them EU member states - in retaliation against the West, in the biggest wave of tit-for-tat expulsions in recent memory.
