Facebook has banned a number of 'far-right' groups, including the British National Party and English Defence League, for violating its rules around promoting hate and violence.
Other groups barred from the platform include Knights Templar International, Britain First and the National Front as well as key members of their leadership.
Former BNP leader Nick Griffin, Britain First leaders Paul Golding and Jayda Fransen, EDL member Paul Ray, Knights Templar International's Jim Dowson and the National Front's Tony Martin have also been banned as part of the crackdown.
The social network says it does not allow groups or individuals which engage in "terrorist activity, organised hate, mass or serial murder, human trafficking or organised violence or criminal activity".
The banned groups will also be blocked from using Instagram, which is owned by Facebook.
Facebook said it uses an extensive process to determine which people or groups it designates as dangerous, using signals such as whether they have used hate speech, and called for or directly carried out acts of violence against others based on factors such as race, ethnicity or national origin.
"Individuals and organisations who spread hate, or attack or call for the exclusion of others on the basis of who they are, have no place on Facebook," a spokeswoman for the social network said.
"Under our dangerous individuals and organisations policy, we ban those who proclaim a violent or hateful mission or are engaged in acts of hate or violence. The individuals and organisations we have banned today violate this policy, and they will no longer be allowed a presence on Facebook or Instagram."
