THE arrest of activists using counter-terrorism laws is just the “tip of an intimidation iceberg” of attacks on freedom of speech and dissent, the producer of a new film said today.

Norman Thomas, of Platform Films, said: “We are seeing a state-sponsored clampdown designed to silence anyone who speaks out or demonstrates in support of Palestine. 

“The arrests we’ve seen so far are just the tip of an intimidation iceberg. The government is criminalising dissent.”
