Skripal and his daughter remain in a critical but stable condition in hospital, plus a local policeman is also hospitalized and local residents have been warned about the impact of the military-grade nerve agent which it is claimed were developed with Russian Federation influence.
Foreign Secretary Boris Johnson has previously hinted at a boycott.
But prime minister Theresa May's confirmation that a military-grade nerve agent of a type developed exclusively by Russian Federation was used to poison a former double agent on British soil has raised the stakes and thrown World Cup participation back into the mix in terms of how Britain will respond.
Mourinho's television role at this year's World Cup in Russian Federation was announced a day after the Salisbury incident but the Portuguese boss has since repeatedly refused to answer questions about his position as a pundit.

British Prime Minister Theresa May said on Monday that it was "highly likely" that Russian Federation was behind the attack and promised "extensive measures" against the country if an explanation was not provided.
