The social networking platform is trying to reduce false news and misinformation on the site, but the company has revealed that politicians are except from the third-party checking process.
Facebook's vice president of global affairs and communications Nick Clegg has outlined the policies, which sees such speech as "newsworthy".
He said in a post: "From now on we will treat speech from politicians as newsworthy content that should, as a general rule, be seen and heard.
"However, in keeping with the principle that we apply different standards to content for which we receive payment, this will not apply to ads - if someone chooses to post an ad on Facebook, they must still fall within our Community Standards and our advertising policies."
Clegg - who was Deputy Prime Minister in the UK from 2010 to 2015 - further explained how Facebook looks to determine what is permitted.
He continued: "When we make a determination as to newsworthiness, we evaluate the public interest value of the piece of speech against the risk of harm.
"When balancing these interests, we take a number of factors into consideration, including country-specific circumstances, like whether there is an election underway or the country is at war; the nature of the speech, including whether it relates to governance or politics; and the political structure of the country, including whether the country has a free press. "In evaluating the risk of harm, we will consider the severity of the harm. Content that has the potential to incite violence, for example, may pose a safety risk that outweighs the public interest value."
