Insiders say all trails lead back to Moscow, suggesting a deliberate act to incite row with UK
The response from the Kremlin has been uncompromising. The foreign ministry described Theresa May’s accusation against Moscow as a “circus show”. Its boss Sergei Lavrov said there was no proof the poison used against Sergei Skripal came from Russia. And the embassy in London promised an “equal and opposite reaction” to any UK measures.
Beneath this bluster, however, is cool calculation. Skripal and his daughter Yulia were poisoned in Salisbury with a Moscow-made military nerve agent, developed during the 1970s and 1980s during the cold war. Whoever wanted to murder him might have used a subtler weapon. Instead, his assassins picked novichok. How it was deployed remains unclear.
