Julian Assange, the founder of WikiLeaks, is making a final attempt in a UK court to prevent his extradition to the United States. His legal team is arguing that he should not be sent to the US, where he faces 18 criminal charges over the publication of US military and diplomatic documents in 2010. If convicted, Mr. Assange could face a maximum sentence of 175 years in prison. His lawyers are expected to focus on his health, claiming that he is not fit to be extradited and that doing so would be in breach of his human rights. The hearing, which is expected to last several days, is being held at the High Court in London. This case is important as it raises significant issues about freedom of speech and protection of journalists who put information in the public domain.
