Meanwhile, the Kremlin says it is sorry to hear of Ms Sturgess' death, but says any suggestion that Russian Federation is involved would be "quite absurd".
Russian ex-agent Sergey Skripal, who received asylum in United Kingdom after being released in a spy Exchange in 2010, and his daughter Yulia were treated for weeks by poisoning with a nervous agent, before receiving medical discharge.
Britain blamed Russian Federation for the poisoning - a charge strongly denied by Moscow which has challenged British authorities to show the evidence.

"We consider that in any case it would be quite absurd".
Dawn Sturgess, 44, died in a hospital in Salisbury, in southern England, police said on Sunday.
The reaction of a couple exposed to novichok in Wiltshire was "so severe" they "must have got a high dose", police have said.

"Our thoughts are also with the people of Salisbury and Amesbury and the Home Secretary will make a statement shortly including on the support we will continue to provide to the local community throughout this hard time". It was reported last night that both Ms Sturgess and Mr Rowley both had traces of Novichok on just one hand.
Prime Minister Theresa May said she was appalled and shocked by the death.
Neil Basu leads counter-terrorism efforts for the Metropolitan Police force. Moscow has denied any involvement. The investigation into attack on Skripal remains open.
Sturgess' death comes as US President Donald Trump prepares this week to travel first to Brussels for a North Atlantic Treaty Organisation summit, then to the London area for meetings with May and the Queen, followed by a meeting with Russian President Vladimir Putin in Helsinki next Monday.
Peskov went on to comment on a separate statement by Russia's representative at the Organization for the Prohibition of Chemical Weapons (OPCW), Alexander Vasilievich Shulgin. "It's hard to escape the thought that everything was pre-planned and deliberately brought about to escalate the global situation and undermine Russia's authority and its ties with other parties".
"It's more Britain's problem and the problem of how much Britain is interested in a real investigation".
