Great Britain will boycott the skiing Biathlon World Cup in Russia in March, with bosses branding Russian athletes "brain-washed" for disowning the McLaren Report.
The board of the British Biathlon Union has voted unanimously to shun March's World Cup meet in the Russian city of Tyumen.
Lawyer Richard McLaren's report claims more than 1,000 Russians benefited from a state-sponsored doping programme between 2011 and 2015, with the London 2012 Olympics "corrupted on an unprecedented scale".
British Biathlon are the latest body to object to competition in Russia, after Lizzy Yarnold threatened to pull out of February's Skeleton World Cup event before it was switched from Sochi to Germany's Konigsee.
"The board of the British Biathlon Union has taken the unanimous decision that Great Britain will not compete at Biathlon World Cup Eight in Tyumen March 2017," read the British biathlon organisation's statement.
"This follows the brain-washed, deluded and dishonest comments of Russian World Cup athletes that McLaren is about politics, not sport and the unprecedented booing of the Russian female athlete who won the sprint at World Cup Two last weekend in Nove Mesto.
"Moreover, the board felt that the whole integrity of the very successful London 2012 Olympic Games has been called into question. Finally, many of the results from Sochi must be regarded as 'a joke'."
The British biathlon bosses have now challenged the International Biathlon Union (IBU) to relocate the World Cup meeting away from Russia.
Biathlon is a gruelling sport that combines cross-country skiing and target shooting, which is hugely popular in parts of Russia.
