"If some officials refuse coming here, it is their personal business," Dvorkovich said, according to news agency Tass. "The history shows that boycotts never led to something good."
Johnson's comments came during continuing fallout over the poisoning of former Russian spy Sergei Skripal and his daughter in the English town of Salisbury this month. Johnson said last weekend that it was "overwhelmingly likely" that Putin was behind the poisoning, which British authorities say used a nerve agent, identified by the British as Novichok, that the Russians developed.
In the aftermath of the attack on Skripal, British Prime Minister Theresa May announced plans to expel 23 Russian diplomats it said had links to espionage. Russia later expelled 23 British diplomats and closed the British Council, a government-backed international organisation for cultural relations and educational opportunities, in the country.
Today, Austin said that the idea of Putin using the World Cup as "a PR exercise to gloss over the brutal, corrupt regime for which he is responsible" filled him with horror.
Johnson has previously suggested that some British officials may boycott the World Cup. However, he said today that it would be wrong to punish British fans or the English football team by banning them from attending the World Cup, but that it would need to have an "urgent conversation" with Moscow about how these fans would be protected.
The Foreign Secretary also told the committee that far fewer Britons had bought tickets so far for the World Cup in Russia than for the previous 2014 event in Brazil. Britain's most senior police officer warned last year that English football fans were at risk of an "extreme level of violence" from Russian hooligans if they attended the sporting event.
Russia's Dvorkovich, who is also chairman of the local organising committee for the games, attempted to downplay such fears. "This will be the best world championship ever," he said. "Our country is very hospitable and we are waiting for everyone here."
