Facebook will lift a ban on political advertising imposed after the US election to curb the spread of misinformation, and has pledged to investigate whether its political ads systems need a further overhaul.

Advertisers would be able to resume running political ads on March 4, Facebook said in a blog post on Wednesday. It said it had introduced the temporary moratorium “to avoid confusion or abuse following Election Day”.
