Yvette Cooper told Trevor Phillips on Sunday that Russia "has had possession of" the rare poison used to kill Navalny， who died in 2024.

Vladimir Putins Kremlin "has had possession" of the deadly frog toxin that was found in the body of Russian opposition leader Alexei Navalny， the UKs foreign secretary has said.

Yvette Cooper also confirmed that the poison - found in the skin of Ecuadorian dart frogs - can also be manufactured in the laboratory and hinted that this could have been the case with the substance alleged to have killed the dissident， who died in a Russian prison two years ago.

She was speaking to Trevor Phillips on Sunday， a day after the UK and a group of allies announced that their scientists had discovered that Mr Navalny， 47， had been poisoned with the frog toxin - called epibatidine.

Classed as a chemical weapon， it is 200 times stronger than morphine and causes paralysis， respiratory failure and death.

Indigenous tribes in South America are said to use the toxin in blow darts or blowguns when they hunt. But it can also be produced synthetically.

Asked whether she could offer any details on whether the poison was manmade or had been taken from frogs， Ms Cooper said: "I can't tell you the details of that. But as you say， this is a particular chemical. It can be produced synthetically.

"It can also be found in this particular frog in Ecuador. And we do know that the Russian regime has had possession of this particular chemical. It is obviously not one that is found naturally in Russia."

She was also asked about the Kremlins response to the claims that it was behind the alleged murder of Mr Navalny， with the Russian embassy rejecting the allegations as nonsense. Russia has previously claimed the death was not suspicious.

Ms Cooper said that Britain， Sweden， the Netherlands， France and Germany had spent the past two years investigating what happened to Mr Navalny at the penal colony in Siberia.

"We have worked with our European partners on pursuing the evidence and pursuing the truth，" she said.

"And that is why we have together found the evidence of this lethal toxin that was found in Alexei Navalny's body at the time he died， and only the Russian regime had the motive， the means and the opportunity to administer this lethal poison while he was in prison in Russia.

"They wanted to silence him because he was a critic of their regime， and that's why we have exposed this barbaric Kremlin plot to do so and made sure that we have done so with evidence."

伊薇特·库珀周日对特雷弗·菲利普斯线路，俄罗斯"曾握有"用于杀害2024年灭一火的纳瓦利内的冷漠毒剂。

英海社交大臣线路，在俄罗斯反对派首领阿列克谢·纳瓦利内体内发现的致命蛙毒，曾被弗拉基米尔·普京指引的克里姆林宫"握有"。

伊薇特·库珀还阐述，这种毒药——存在于厄瓜多尔箭毒蛙皮肤中——也可在履行室中合成，并示意两年前死于俄罗斯监狱的异议东谈主士，其死因所涉物资可能正属此类。

周日，她与特雷弗·菲利普斯进行了交谈。就在前一天，英国过火友邦告示，他们的科学家发现47岁的纳瓦利内先生遭到一种名为epibatidine的蛙类毒素构陷。

该物资被列为化学火器，其强度是吗啡的200倍，可导致瘫痪、呼吸痛楚乃至死一火。

据悉，南好意思洲的土著部落狩猎时会使用吹箭或吹管中的毒素。不外这种毒素也能通过东谈主工合成获取。

当被问及能否提供关连毒药是东谈主造已经从青蛙身上索求的瞩目信息时，j9game库珀女士线路：“我无法显现具体细节。但正如你所说，这是一种稀奇化学物资，不错通过东谈主工合成形态制造。”

这种稀奇化学物资也存在于厄瓜多尔的特定蛙类中。咱们照实知谈俄罗斯政权曾握有该化学物资。彰着，这种物资并非俄罗斯原土当然存在的。

她还被问及克里姆林宫对关连其涉嫌参与纳瓦尔尼谋杀指控的复兴，俄罗斯大使馆挑剔这些指控熟谙天方夜谭。俄方此前曾宣称纳瓦尔尼之死无可疑之处。

库珀女士线路，英国、瑞典、荷兰、法国和德国已往两年一直在看望纳瓦利内在西伯利亚放逐地遇到的事件。

她线路：“咱们与欧洲伙伴共同致力，追寻左证，查明真相。”

正因如斯，咱们共同发现了阿列克谢·纳瓦利内物化时体内存在的致命毒素左证。那时他正被关押在俄罗斯监狱，只须俄罗斯当局具备动机、时代和契机对其施放这种致命毒剂。

他们企图让他噤声，只因他是其政权的品评者。正因如斯，咱们才揭露了克里姆林宫这一霸谈计较，并确保所有指控均附有可信左证。
