DWYFOR Meirionnydd’s MP has challenged the prime minister about nuclear materials following the suspected attempted murder of a former Russian double agent and his daughter.

Sergei Skripal and his daughter Yulia were in Salisbury earlier this month when both were found in a critical condition on a public bench.

It has since transpired that both had been inflicted with a nerve agent which has left both, and a police officer who attended, fighting for their lives.

The incident has sparked a marked decline in UK and Russian relations.

It has been suggested that Russian involvement was “the only plausible explanation” but the Kremlin has denied responsibility.

In a meeting in the House of Commons last week, Theresa May gave an update on the situation, prompting MP Liz Saville Roberts to challenge the Prime Minister regarding trade of nuclear materials with the former Cold War adversary.

Mrs Saville Roberts said: “Alongside many colleagues in the House, I speak on behalf of my party in calling for a robust and immediate response.

“Sources inform us that Russia is the UK’s biggest weapons-grade nuclear substances export market, despite several attempts at a moratorium on depleted uranium by the European Parliament and the United Nations.

“Will the Prime Minister confirm whether the UK is still exporting nuclear substances to Russia?

“If so, surely this should be among the very first sanctions imposed?”

In her response, the Prime Minister said: “I thank the hon Lady for her remarks and for the support that she has given from her party for the actions that the Government are taking.

“What we have been talking about today is the use of a nerve agent – of a chemical weapo – on UK soil and ?the blatant flouting of the international rules-based order and legal structure around that use of chemical weapons by the Russian state.”
