Prime Minister of the United Kingdom, Theresa May, on March 14, had ordered the Russian staff to pack their bags amid heightening tensions with Moscow, claiming London diplomats were 'undeclared intelligence officers', according to The Independent.
He added that nearly half of the embassy's employees were to leave the country.
"These people are regular diplomats, 40 percent of the embassy's staff. The embassy has never been overmanned since the Britons have always been practising expulsions. So, the staff has constantly been decreasing," Yakovenko had said.
"Naturally, further expulsions will reduce the embassy's possibilities, first of all, as far as consular services are concerned. It will create certain problems but most of us understand where we are working and in the current situation each diplomat is ready for any unexpected developments," he added.
The British Prime Minister gave a week's time to the diplomats for leaving the country.
Britain will also cancel high-level contacts with Russia, May had said.
