Re: yulia skripal
It is the father they are trying to kill, but I suspect her visit to see him led them to where he was living.
Sadly I believe she still has family in Russia and that is why she wants to return, but it must also be difficult having to live in a country where they even use a different alphabet to what you have been brought up with.
Her dad is only here because he spied for Britain, was imprisoned & released on a deal with us. He may have knowledge that would be useful to us, so was kept here, but his daughter was a free citizen of Russia who probably was only poisoned because she touched the stuff they were trying to kill him with.
Ask yourself, would you want to return to a country, where your family lived, when they had tried to kill you father because he had spied for Uk and you had got caught up in the murder attempt.....remembering that your husband and children still lived in your home country?
