The social media company Reddit said it has detected a suspected Russian disinformation campaign on the site intended to spread confidential U.K. government documents ahead of next week's election.

That comes after social media analytics firm Graphika suggested in a report earlier this week that Russian tactics played some role in the leak of the documents last month, which detailed U.S. and U.K. discussions leading up to Brexit.

The documents showed that U.S. officials wanted the U.K.’s National Health Service to be “on the table” in any post-Brexit talks — a claim that bolstered an attack line by the opposition Labour Party and fed allegations that the Conservatives were putting the system up for sale.

Asked Saturday whether Labour had somehow benefited from a Russian trolling operation, leader Jeremy Corbyn said: “This is such nonsense. This is such an advanced state of rather belated conspiracy theories by the prime minister.”

Conservative minister Nicky Morgan told the BBC it was "extremely serious" that the leaked documents might be linked to a Russian disinformation campaign, adding that "actually as culture secretary, obviously one of the things that we are looking for and monitoring is any interference in our elections."

“I do think we need to get to the bottom of that,” Prime Minister Boris Johnson told Sky News.

Labour sought to use the findings to push the government to release a report detailing Russian interference in U.K. elections, which the Conservatives said they won’t do ahead of the upcoming election.

“If we want to get to the bottom of the extent to which the Russian state interferes in elections, can we please publish the intelligence and security committee report? Let’s get that out there. That should have been published ages ago,” Andy McDonald, the shadow transport secretary, told the BBC.

In a statement outlining how it tied the latest campaign back to Russia, Reddit said it believes the post was connected to similar disinformation efforts that Facebook discovered earlier this year.

In an analysis of the earlier campaign, which Facebook took down in May, the Washington think-tank the Atlantic Council called the operation the "Secondary Infektion."

"The operation was strongly reminiscent of the Soviet-era 'Operation Infektion' that accused the United States of creating the AIDS virus," according to an Atlantic Council blog post at the time. "The latest operation ... used a similar technique by planting false stories on the far reaches of the internet before amplifying them with Facebook accounts run from Russia."

The Atlantic Council said the size, scope and sophistication of the effort suggested it was developed by an intelligence operation.

Reddit said Friday that it confirmed "a pattern of coordination" that linked the recent suspicious post on its platform to the much larger campaign on Facebook. Suspicious accounts on Reddit linked to the post "have the same shared pattern as the original Secondary Infektion group detected, causing us to believe that this was indeed tied to the original group."

The company said it banned one "subreddit" discussion forum and 61 accounts as a result of its investigation.
