Both Skripal and his daughter are in critical condition and doctors aren't sure if they'll survive.
Intelligence agencies now believe the nerve agent used on the pair was planted in the daughter's suitcase before she left Moscow, the Daily Telegraph reported late Thursday. "There is to be no Russophobia as a result of what is happening", Johnson said on Friday.
Theresa May announced on Wednesday that 23 Russian diplomats will be expelled from the United Kingdom and a range of other measures taken against Moscow, including detaining suspected spies at the United Kingdom border, increasing checks on private flights and freezing some Russian state assets.
"We call on Russian Federation to live up to its responsibilities as a member of the UN Security Council to uphold worldwide peace and security".
Foreign Minister Sergei Lavrov said Russian Federation would respond by expelling British diplomats "soon".

He slammed people "distributing information that the programme allegedly existed", an apparent reference to Soviet chemist Vil Mirzayanov, who first revealed the existence of that class of ultra-powerful nerve agents.
Foreign ministry spokesperson Maria Zakharova said May's statements were "completely insane accusations", and accused Britain of failing to work with Moscow through the OPCW.
Russian Federation has complained that it has had no access to nerve agent to be able to analyse it.
British Foreign Minister Boris Johnson is scheduled to brief his European Union counterparts at a March 19 meeting of the bloc's Foreign Affairs Council.
