Ben Wallace told the BBC on Thursday that Putin and his government “controls, funds and directs the military intelligence” unit known as the GRU that Britain believes used Novichok to try to kill ex-Russian spy Sergei Skripal and his daughter Yulia.
Britain plans to press its case against Russia in the U.N. Security Council Thursday. Many Western countries have already imposed sanctions on Russia because of the attack.
Walls said the GRU is directly linked to Russia’s Defence Ministry, the Kremlin and Putin’s office.
