The man in the middle and right picture is supposed to be Ruslan Boshirov, one of the two Russians who say (vid) that they went to visit Stonehenge via Salisbury on March 3 and March 4 2018, but could not reach it because the roads were closed after recent snowstorms. (Stonehenge was indeed closed during those two days.)
The British government asserts that the two visiting men are agents of the Russian military intelligence service GRU. It says that they applied 'Novichok' to the doorknob of Sergej Skripal's house with the intent to kill the former British spy. The 'highly deadly' poison is said to have affected Sergej Skripal, his daughter Yulia and a policeman. All are said to be well by now but all three have been vanished from the public by the British intelligence services.
