Russia on Saturday demanded that Britain further reduce its diplomatic staff in Moscow, the latest move in an escalating tit-for-tat dispute following the poisoning of a former Russian spy on British soil. Russia had already kicked out 23 British envoys and closed a British consulate in response to the expulsion of 23 Russian diplomats by Britain, which accuses Moscow of poisoning former double agent Sergei Skripal and his daughter in the English city of Salisbury on March 4.
