Self-styled free speech activists in the United Kingdom have found a fierce ally in Elon Musk as concerns about government censorship span continents. 

Musk inserted himself into U.K. politics at the turn of the new year when he called for Tommy Robinson, a British activist characterized by critics as anti-immigrant and anti-Muslim, to be released from prison. Robinson has become the face of an anti-censorship movement in Great Britain after he was targeted by the government for spreading what it deemed hate speech and disinformation, particularly relating to Muslims and Islamist extremists.
