Salisbury spy poisoning is a 'distraction from Brexit' - Russian foreign minister
Russia's foreign minister accused Britain and the US of spreading "lies and disinformation" about the poisoning of a Russian ex-spy in England, declaring that East-West tensions are worse now than during the Cold War.
Britain has blamed Russia for the March 4 nerve agent attack on former double agent Sergei Skripal and his daughter, Yulia.
Britain and two dozen of its allies have since expelled over 150 Russian diplomats. Moscow, which vehemently denies any involvement, has responded tit-for-tat.
Russian Foreign Minister Sergey Lavrov denounced the British accusations on Monday as a "mad and horrible provocation".
He argued that Russia had no motive to attack Mr Skripal, who was released in a 2010 spy swap from a Russian prison where he was serving time for spying for Britain.
"If there were any gripes against the man, he wouldn't have been swapped," Mr Lavrov said.
Russia's top diplomat also mocked Britain's claim that there was no plausible alternative explanation for the poisonings of the Skripals.
British intelligence agencies could have been involved and the case helped distract public attention from the British government's difficult talks to exit the European Union, Mr Lavrov said.
"There are other explanations besides those put forward by our Western colleagues, who declare that it can only be the Russians who are responsible," Mr Lavrov said. "It could also be advantageous to the British government, who clearly find themselves in a difficult situation having failed to fulfil their promises to voters over Brexit."
British officials have previously rejected similar Russian allegations.
Mr Lavrov said that Russia has called a meeting of the international chemical weapons watchdog for Wednesday to discuss the case and asked it to provide details of its cooperation with Britain in the poisoning probe.
Alexander Shulgin, the Russian representative at the Organisation for the Prohibition of Chemical Weapons (OPCW), said on Monday in televised remarks that the organisation must conduct an "open, thorough and unbiased investigation" with Russian experts' participation.
British authorities invited OPCW experts to take chemical samples from Salisbury, the English city where the father and daughter were sickened, and to analyse them.
Mr Shulgin warned that Moscow would not accept the agency's conclusions unless Russian experts are allowed to take part in the process.
Mr Lavrov also assailed the British authorities for stonewalling Russia's request for consular access to Yulia Skripal, 33, a Russian citizen whose condition has improved since she and her father fell critically ill on March 4.
"Many say that the situation now is worse than it was during the Cold War because some rules existed and decorum was observed back then," he said.
"Now, Britain, the US and a few countries blindly following them have dropped all decorum and engaged in blatant lies and disinformation."
